SNMP Alert

[corrado68]

Hello,

I have one SNMP GET test that monitor the temperature environment, the reply of test have this format : "19.00 Centigrade". I try to have one alert using Alert when OID is > 25 or using '25' but it doesn't work.

How can I have an alert when the reply is a string and not a number ?

Thanks

When device returns String reply, HostMonitor will compare values as strings.
E.g. if you will set Alert when OID is > 25 and reply will be
string 27.00 Centigrade test should return "Bad" status.
However, if device will return 9.00 Centigrade test also will return "Bad" status (because string 9.00 Centigrade is > then string 25)

In many cases, devices have several OID's that return the same information
in different formats.
What exactly OID do you use to check temperature ?

Hi,

I get the temperature from one IBM RSA and use the OID 1.3.6.1.4.1.2.3.51.1.2.1.5.1.0

As I can see all temperature counters returned by IBM RSA have OCTET STRING type.
Also, description of OID 1.3.6.1.4.1.2.3.51.1.2.1.5.1.0 says:

"System's ambient temperature in degrees centigrade(C).
This is surrounding temperature where the system is installed.
An octet string expressed as 'sddd.dd Centigrade' where:
s is the sign ('-' for negative or blank space for positive)
d is a decimal digit or blank space for a leading zero..
The string 'Not Readable!' indicates that the given monitor
is not supported on this system."

That means OID returns value " 19.00 Centigrade" with two spaces before 19.00 Centigrade
You should try to set Alert condition with two leading spaces and without quotemarks.

Yes, that counter returns string and I do not see similar counter that return integer or opaque data (that can be converted to float number)
