MIB Browser is an auxiliary application for HostMonitor, however it can be used independently as well.
It is included into Advanced Host
Monitor package (since version 5.70);
it can also be downloaded separately at download page
MIB Browser allows you to view the hierarchy of SNMP MIB variables in the form of a tree and provides you with
additional information about each node.
With MIB Browser you can easily load (compile) proprietary MIB files, view and manipulate data provided by local or remote
SNMP agent - MIB Browser may retrieve counters value from specific SNMP agent, display tables, show system information and real-time charts.
When you are configuring SNMP Get,
or SNMP Trap
test methods with MIB Browser installed HostMonitor allows you to specify SNMP variables by
a name (e.g. iso.org.dod.internet.mgmt.mib-2.system.sysUpTime.0) as well as by an OID in
numeric format (e.g. 18.104.22.168.22.214.171.124.0).
If you click on "Browse MIBs" button next to "OID" field, HostMonitor will launch MIB Browser displaying the hierarchy
tree of SNMP variables. The specified variable (if any) is highlighted and additional information is displayed for it
(such as status, access mode, description). Now you may browse variables, choose another variable if needed and click
[Ok] button to use the selected variable by HostMonitor.
Also, by using a database of compiled MIB files HostMonitor may translate OID from its numeric form to the MIB name for
received SNMP Trap messages. In such case MIB Browser is needed when you want to extend a database to include
information about MIBs supported by some specific SNMP enabled device (e.g. your CISCO 1603 router).
Note: you may find IP-Tools' SNMP Scanner utility useful for your needs. SNMP Scanner allows you to scan a range
or list of hosts performing Ping, DNS and SNMP queries. For each SNMP responding device the scanner displays additional
Interface of the browser is simple and straightforward so we note just few key points:
Main screen displays the hierarchy of SNMP MIB variables in the form of a tree and provides you with the following
additional information about each node of the tree:
- Press "+" or "*" to expand a tree node. If you press "+", immediate sub-nodes of the selected node will be displayed. If you press "*", all descendants of the immediate sub-nodes will be expanded as well. When the node is expanded the [-] button appears next to the node name.
- To collapse a tree node press "-". When a node is collapsed, all of its sub-nodes are hidden and the [+] button will be displayed near the node name.
Popup menu helps to retrieve value of the selected counter:
- Get value
- Get next
- Get row
- Get table
|Allows you to perform operations with MIB files and MIB database (the database stores information about all compiled MIB files). This menu is disabled when MIB Browser is started while you were editing a HostMonitor's test item.|

This utility may request data from target SNMP agent: it may retrieve single counter, get all instances of the multi-instance counter,
display up to date system info, etc.
First you need to specify target system address, port, SNMP profile, then choose OID to request.
The object identifier which uniquely identifies the object for requesting (e.g. 184.108.40.206.220.127.116.11.0). MIB Browser sets
this field automatically using the selected MIB variable, however you may change the automatically assigned value.
After specifying above parameters you may perform the following actions:
Retrieves value of the specified variable.
Please note: If you are requesting a single instance counter, add ".0" to the OID. Otherwise make sure that you have
specified a valid index or use the Get Next request instead (if you don't know the index).
This operation is useful when you need to retrieve variables from within a table. If you select multi-instance counter, this
function will retrieve all instances of the counter. E.g. Get Row 18.104.22.168.22.214.171.124.1.10 will retrieve the total number of
octets received on EACH network interface installed on target system.
For single-instance counters this function works similar to Get function.
Retrieves one or several SNMP variables following the specified OID. With this operation, you don't need to know the exact variable index.
The SNMP agent searches sequentially to find the needed variable within the database.
For a numeric counters you may use "Chart" function - display counter value as real-time charts.
Connects to target SNMP agent and retrieves up to date system information such us OS description, uptime, disk free
space, memory usage, network interfaces.
Searches for last requested OID in the MIB tree, selects the counter and displays information about the variable.
Simply closes "SNMP Get" window (returns focus to main window or chart window)
This MIB Browser utility connects to target SNMP agent and retrieves current values of all counters that belong to specified table.
E.g. if you select ifTable element, MIB Browser will display detailed information about all network interfaces installed on target
device, including interface description, physical address, speed, admin and operational status, total number of octets received on
the interface, errors and so on.
Popup menu allows you to copy all fields within selected column or row into clipboard, copy entire table into clipboard, copy
OID related to selected cell. For a numeric counters you may use "Chart" menu item - display counter value as real-time charts.
This utility displays real-time charts for one or several counters (up to 4 counters). You can choose counters using main window,
SNMP Get window or Table window. MIB Browser may monitor counters provided by one or several SNMP agents, e.g. you may see traffic
on your server and your router at the same time.
You may set refresh rate, pause and resume monitoring, choose color palette, set one of the following visualization modes:
Also popup menu offers "Copy data" option - copies data into clipboard.
- Counter value
- Value change
- Value change /sec
- Percentage change
Save profiles / Load profiles
This option allows you to save current settings into file. MIB Browser stores list of counters, refresh rate, visualization mode.
Then you may load stored profile at any time using "Load profiles" button or using main window menu View->Charts.
In order to connect to remote SNMP agent the following parameters should be specified:
A string specifying either a dotted-decimal IP address or a host name that can be resolved to an IP address (e.g. 126.96.36.199).
UDP port used by target SNMP agent (default port for SNMP requests 161)
This is the amount of time in milliseconds the program will wait for a response from SNMP agent before the request fails.
Specifies the communications retry count
Choose SNMP credentials profile
SNMP Credentials dialog allows you to setup list of SNMP profiles (accounts). Profiles store login or community string and other
information necessary for communication with SNMP agent.
For each profile you should specify name of the profile (your choice) and version of SNMP protocol used by SNMP agent. MIB Browser
supports SNMP v1, v2c and v3.
If SNMP agent uses SNMP v1 or v2c protocol, specify the SNMP community name (often SNMP agents use "public" as community string).
If SNMP agent is configured to use SNMP v3, you should specify the following parameters:
Enter the username that is configured for the SNMP agent(s). An SNMP device, upon reception of a request, uses this username
to look for configured authentication and encryption parameters and applies them to the received request message.
Specify the context needed to identify specific SNMP instances. This parameter is optional.
You may choose one of the following authorization methods: None (no authorization), MD5 or SHA authentication.
If authorization is used, use this field to specify authorization password.
Specify encryption mode: DES, AES or 3DES
Specify key for encryption
When you install Advanced Host Monitor package, then all applications (MIB Browser, HostMonitor, DiskMeter, RCC) use the same set of
SNMP Profiles stored in snmpacc.lst file. You may modify profiles using HostMonitor or RCC application. MIB Browser and DiskMeter
does not allow modifications so operator without necessary rights cannot change profiles.
When MIB Browser (or DiskMeter) installed as standalone application, it allows SNMP credentials modification, profiles stored in
