We've just upgraded to Hostmon Professional to get the MIB Browser and do our first SNMP tests. I'm having problems querying the values I want however.
The two values I need to read are in a table in the SNMP device.
The OID for the table is: 1.3.6.1.2.1.2.2.1
And the particular field I need is: 1.3.6.1.2.1.2.2.1.8
So the OID's I actually need to query for the two records I'm interested in are:
1.3.6.1.2.1.2.2.1.8.3
1.3.6.1.2.1.2.2.1.8.4
In the MIB browser I can query these OID's fine, they return 1 or 2 to indicate the status of the line. However when I return to Hostmonitor I can't query them. As soon as I click the 'get value' button it appends .0 to the end of the OID and returns the error "SNMP error: No such name".
I'm very new to SNMP, but my guess is that it's appending .0 when it doesn't need to. From reading around this, the .0 is the correct way to refer to single values when performing a GET query, however if you're reading values from a table instead of 0 you pass the ID number of the row you wish to read.
I'd very much appreciate it if someone can tell me how to query these values - these two queries are the reason we upgraded to the pro version
If this is as I think and hostmonitor is appending .0 when it doesn't need to, would it be possible to update to the code so that when 'get value' is pressed it first tries to query the OID directly, and tries again with .0 appended if the first attempt fails? That would keep the ease of use for SNMP newbies, while allowing table values to be queried properly.
