Improvements  HostMonitor/RCC GUI improvements

SuperMatrix: more visualization options

SuperMatrix window may provide additional information for each test item SuperMatrix settings

  1. up and/or down trends based on average reply value of the tests items. HostMonitor may check and compare several time intervals:
    - compare this and last hour
    - compare today and yesterday
    - compare this and last month

  2. up and/or down trends based on availability ratio of the tests items (good/bad status ratio). HostMonitor may check and compare several time intervals:
    - compare this and last hour
    - compare today and yesterday
    - compare this and last month

  3. display reply value as log base 2
    - current reply
    - hourly average
    - daily average
    - monthly average

  4. display test method icon for each test item; display icons just for bad/unknown/warning test items; display icons for specific test method
You may mark two or all three options, in this case "trends" option will be prioritized and lowest priority will be set to "icons" option. So reply marks will be displayed when trend does not reach specified limit and icons will be displayed when test reply value is empty (or reply option is set for another test method).

SuperMatrix profiles

You may setup 10 profiles and switch between profiles with one click.
For example you may
  • use one profile in order to display up and down trends for Ping tests based on average reply values gathered today and yesterday with 10% up-threshold and 5% down-threshold
  • use another profile in order to display up and down trends for all tests based on availability ratio of this and last month with 5% up-threshold and 2% down-threshold
  • 3rd profile: display current reply for CPU Usage tests and show icons for other test methods
Each operator may set its own profiles. Also admin may setup default profiles for all operators that did not set personal profiles yet ("admin" in this case operator with "edit GUI options for all accounts" permission)

SuperMatrix: quick switch

Also you may temporarily override profile settings and display just trends or reply value or icons for ALL test methods. You may use popup menu items or hot keys: Ctrl+E (show icons); Ctrl+R (show reply values); Ctrl+T (show trends). HostMonitor will use limits and time period specified for current profile but will apply selected option for all items (even if the profile set to show trends just for memory test, for example); also it will display icons regardless of test status and size of the cells.
You may press the same hot key (or use the same menu item) in order to deactivate "quick switch" mode and activate profile settings again. Or just switch to another profile when needed.

SuperMatrix: current color palette

This option turns off bright green-yellow-red cells colors and tells SuperMatrix window to use current palette. Also "icons" mode works differently in this case, images will be selected based on test method AND test status.
dark mode dark mode

RMA agents list

  • Works fater with large lists
  • Added "find" (Ctrl+F) and "search again" (F3) options

New variables
  • %AccountSet% variable returns username set for the test item (including URL, HTTP, OPC, SOAP, Mail Relay, Apache, NGINX, Tomcat, POP3, IMAP tests)
  • %uuu% variable returns UnixTimeStamp (seconds since 1970)
  • new options for date expressions: [-0u] converts local time to UTC time. E.g. %yyyymmdd-hhnn[-0u]% %uuu[-0u]%

Fixed  The following issues were resolved

  • HostMonitor and RMA for Windows: NT Event Log test method could use a lot of memory when thousand of new records fit filters and "report about all good/bad events" option is used. Fixed
  • Web Service: web interface in some cases did not ask for login after logout operation (new browser session was required for new login). Fixed


Improvements  HostMonitor improvements

  • When you set a lot of test items with private log files (e.g. 20,000 unique log files) and Windows Defender is active, then the antivirus may significantly slow down HostMonitor. The new version works much faster in such cases and the load on the system caused by the antivirus software is reduced. However we still recommend excluding log and report files from the antivirus check.

  • New "undocumented" hostmon.ini options allow you to set logging pools size (pool for common log and pool for all private logs) You may add one or two lines in [Logging] section of hostmon.ini file and restart HostMonitor. E.g.
    CommonPoolSize=40960
    PrivatePoolSize=10240
    Note: the minimum size of each pool: 4096

Fixed  The following issues were resolved

  • HostMonitor: some corrections related to %TrapAllValues_NameValue% and %TrapAllValues_NameValueShort% variables
  • Web Service: in some cases web interface could translate user comments using lowercase letters for all words (e.g. when operator disables test item). Fixed
  • Web Service: acknowledge operation could save only 1st line of the comment. Fixed


Improvements  HostMonitor improvements

  • Advanced mode action and variables like %AckRecurrences%, %AckComment%, etc allow starting special actions when Bad test status was acknowledged by the operator. Such actions could be started after the following test probes while sometimes you may need to start action right after acknowledgment. Yes, you can force HostMonitor to perform any test right now and this will trigger action execution (according to the expression) however some improvements can be done. So we added new useful option: if you set advanced mode action using %AcknowledgedJustNow% variable, then HostMonitor may trigger action when operator acknowledges test status without waiting for the next test probe. This way you may pause or disable test (if you need) right after acknowledgement and still trigger special action(s).
    For example, you may use expressions like
    %AcknowledgedJustNow% and ("%Reply%" > "90 %")
    %AcknowledgedJustNow% and (("%AckComment%" getword 1)=="Attention")

    Note: HostMonitor may trigger such action even if operator chooses "acknowledge and STOP alerts" option; "New ack comment" operation may trigger such alerts as well.

Improvements  GUI improvements

  • Experimental RCC_Theme application - Remote Control Console with themes support. You may choose various dark and light themes: black, glossy, grey, glow, onyx, light, silver, saphire, win10, etc.
    What is the difference between color profiles and themes? Color profiles allow customization of test item colors (depending on test status) for GUI, HTML reports and log files while using Themes you may change application look: window title, menus, buttons, controls and so on.
    When non-default theme set then you may adjust just font color for various test items (Bad, Ok, Unknown, Warning, etc); you cannot change background color in this mode.

  • Various HostMonitor/RCC GUI improvements

Fixed  The following issue was resolved

  • In some cases SLA reports with charts could fail (since v 13.00). Fixed


Improvements  HostMonitor improvements

  • Minor optimization
  • Modified TestInfo window
  • Modified Info pane shows status duration, rise or drop of test result like "512 GB (-20 GB)", previous status, previous reply, min, max and average reply for several periods [this hour / today / yesterday / this month / since reset]
  • New dynamic icons for "Icon" mode...

    dynamic icons


Improvements  HostMonitor improvements

  • Redesigned mailer allows to send more e-mails using less resources.
    However we recommend to use Master-Dependent test relations, this way some general network failure will not lead to thousand actions triggered at once

  • Better protection from DDoS attacks on TCP port used for communication with Active RMA agents. However we still recommend to use firewall or HostMonitor filters (Options dialog -> Active RMA server -> Accept connections from the following IP addresses)

  • Optimized built-in server for Active RMA agents works about 10% faster


New features  HostMonitor and RMA for Windows

  • new test methods
    - SonicWall CPU usage
    - SonicWall Memory usage

Improvements  HostMonitor and RMA for Windows
Improvements  Web Service
  • supports Views based on logical expressions. The following 84 variables supported (other variables offered by HostMonitor and RCC GUI not supported by Web Service)

Fixed  The following issue resolved

  • %FolderCurrent_TotalTests% and %FolderRecursive_TotalTests% variables could return 0. Fixed


Improvements  URL test improvements

  • "Download nested frames" option checks if src parameter of the frame/iframe tag set to "about:blank" and there is "data-lazy-src" option. In such case HostMonitor checks URL specified in "data-lazy-src" parameter (there is no such parameter in HTML specifications but its often used by JS code)

Improvements  SSH test allows you to check result of the command execution in 4 different ways:
  • Exit code - checks exit code (error level) returned by the program. Reply field shows exit code
  • Text (show code) - checks for specific strings or expression in the command output. Reply field shows exit code (error level)
  • Shell script result - checks the command output for specially formatted result string
  • Text output - checks for specific strings or expression in the command output, Reply field shows command output

Improvements  File/Folder Availability test
  • %object2% variable provides target path (path without file name)

Fixed  Several minor issues related to detailed historical charts were resolved


Improvements  Web Service: new authentication methods

  • HostMonitor authentication
    Web browser will prompt for user name and password, operator should type user name and password set on HostMonitor side (menu User -> Operators).
    Traffic between browser and Web Service is not secured (unless HTTPS is used). Traffic between Web Service and HostMonitor are secured (just like HostMonitor<->RCC or HostMonitor<->RMA traffic).

  • Windows or HostMonitor authentication (priority: Windows authentication)
    If remote operator logged on to the domain, web browser will try to get access to Web Service using Windows authentication mechanism (Kerberos). HostMonitor user account with the same name should be set with "HM or Windows authentication" option and both HostMonitor and WebService processes should be started on the same system (domain member).
    Otherwise browser will prompt for user name and password and HostMonitor authentication will be used.

  • HostMonitor or Windows authentication (priority: HostMonitor authentication)
    Web browser will prompt for user name and password. However If remote operator logged on to the domain and HostMonitor user account with the same name set with "HM or Windows authentication" option and both HostMonitor and WebService processes are running on the same system (domain member) then you can type WindowsAuth instead of user name and web browser will be able to connect to HostMonitor using Windows authentication mechanism (Kerberos).

You may set allowed authentication mode using Web Service menu Options -> Authentication
See also Kerberos notes and browser settings

Improvements  HostMonitor improvement

  • Optimization, about 5% better performance on high load


Improvements  HostMonitor improvements

  • Sometimes antivirus (e.g. Windows Defender) may use a lot of system resources during checking of HostMonitor's "system" and "user operations" log files (especially when HTML file format is used). We modified logging module, this helps to reduce system load caused by antivirus software. However we still recommend to exclude log and report files from the antivirus check.

Fixed  The following issues were resolved

  • Built-in backup tool: sometimes HostMonitor could remove recent backup copies instead of oldest copies. Fixed
  • Minor historical charts corrections
  • Minor RCC corrections


Improvements  HostMonitor and RCC improvements

Historical charts improvements
(Test History, Network map, Super matrix, Sysinfo windows)

1) Detailed mode for Performance charts
History-related windows may display charts using 2 modes:

  • brief (works without log files, supported since version 8)
  • detailed (new mode, requires new kind of logs: compact logs)

HostMonitor automatically chooses detailed or brief mode for charts. If you just installed HostMonitor version 13, there are no data yet so Brief mode will be used. After 5-10 minutes HostMonitor may switch to Detailed mode for some time intervals (Today; Last 24 hours). In couple days HostMonitor may enable Detailed mode for [Yesterday], [Last 48 Hours], [Last 7 days], [Last 14 days] time intervals. And finally Detailed mode will be enabled for [This month], [Last 30 days], [Last moth], [Last 60 days] intervals.
Note #1: [This year], [Last year], [Last 12 months], [Last 24 months] - only brief mode supported for such time intervals.
Note #2: If you disable compact logs, only brief mode will be used.

Test History window improvements

2) RCC (Remote Control Console) may show time offset in History window title (when time on HostMonitor system is different from RCC time)

3) Zoom/Unzoom operations adjust time labels. Various formats can be set depending on selected time interval:
  • day of the month
  • day of the week (day of the month)
  • day of the week
  • day of the week hh:mm
  • hh:mm
  • hh:mm:ss
(note: you may zoom in chart when single test item selected)

4) Charts can be updated by timer so you may keep Test History window open and you will see updates. Refresh rate depends on selected time interval: 5min for daily charts; 1 hour interval for weekly charts; 2 hours interval for monthly charts.

5) New popup menu items tells HostMonitor to copy raw data from chart into clipboard
  • Copy to CSV
  • Copy to CSV all tests (available when several tests displayed)

6) New popup menu item: Show min values -> Auto, On, Off modes

7) If you open Test History window for 2 or 3 selected test items, charts will be located one below another. Horizontal mode allows to see more details on the charts
cpu charts

8) "Same scale for all" option was replaced with "same scale for groups", it sets the same scale for groups of selected tests. For example:
  • if you select CPU Usage and Drive Free Space test and open Test History window, then HostMonitor will use one scale for CPU tests and another scale for drive free space tests
  • if you open Test History window for Drive Free Space tests some of which use GB units while others display percent of free space, then HostMonitor will use one scale for tests with "%" units, other scale for tests with "GB" units
  • if you open such window for CPU Usage, Ping, Trace and Traffic Monitor test items, then HostMonitor will use one scale for Traffic Monitor tests, another scale for CPU+Ping+Trace test items

9) Other minor improvements

traffic charts



Compact logs
If you are using Brief or Midnight mode for Primary/Backup log files while you need detailed historical charts (Test History, SysInfo, SuperMatrix, NetMap windows), you may enable Compact logs. HostMonitor will store extra data in specified folder, keep results related to last 2 months and remove older data.
If you are using Full logging mode for Primary log file, you still may like detailed charts because HostMonitor charts can be displayed within 1 second while Log Analyzer may need a minute in order to parse large log files.

Disk space requirements
If you set 100,000 test items and HostMonitor performs over 1,000 tests per second, such data files may consume about 10GB of disk space.
If you set just 5,000 test items and perform 50 tests/sec, then data files will consume about 500MB of disk space.

See Options dialog -> Log settings -> Compact logs page



Auditing Tool improvements

Log Files page
Some customers have just 2-3 log files - one log file with test results (common log), single system log file and user operations log.
Other customers may have thousand log files:
  • common log file(s) with test results, changed monthly, weekly or daily
  • private log files for 30,000 test items (each of 30,000 logs can be changed on regular basis as well if you are using file name like %TestID%-%yyyymmdd%.log)
  • system log files (can be changed on regular basis as well)
  • user operation logs
  • compact log files
There are log processing options but some customers do not setup HostMonitor to remove old log files automatically and keep 500,000 forgotten log files.
Auditing Tool finds and displays all log files in a single table. It shows file name, size, age, type of the log and location. In some cases it shows summary - single record with size of all *.txt or *.clg files in the folder.
You may sort items by any field (e.g. name, size, age) and use popup menu items in order to remove unnecessary files.

Auditing Tool



Various GUI improvements related to the following windows
  • Mail Profiles
  • Action Profiles
  • Report Profiles
  • Recent Events
  • Auditing Tool
  • SNMP Credentials

Minor performance improvements

HTTP Request action: you can add hmvars: text HTTP header into HTTP/HTTPS request. In this case HostMonitor will not encode variable values, will not apply JSON or HTML encoding rules



Fixed  The following issue was resolved

  • E-mail test method: under some conditions HostMonitor could repeat test again and again every second. Fixed
