Need a way to tune SNMP response time

Sun Apr 22, 2007 5:29 am

I have a couple of devices that have poor SNMP performance. If I try to query 20-30 OIDs within a function, data is only displayed for the first 10-15 or sporatically for some.

I have several sets of functions (one per device type) that I have added to the map->tooltip. The functions query a specific OID to see if it is the correct device and then queries several OIDs to display data when you hover over an element on the map. For these slow devices, the query for the specifc OID doesnt even work so no function data is displayed for them.

Anything that can be done?

For an enhancment, it may be nice to be able to specify a tooltip as part of the device definition itself so you wouldn't have to query for device type first.

For the performance issue, maybe a tool that can measure snmpget response time per OID and then set the response time a table per IP?

We will make additional options in snmp profile - 'try count' and 'try
timeout' that will apply to all snmp queries using that profile.
Currently it is hard set to 3 tries and 3000 milliseconds for each try.

Thanks Uldis. Can the parameters be set on Device type instead of or in addition to the SNMP profile? Or should we just make a specific profile for slow devices?

Can you make 2.2 version with higher timeout, like default set 3.0b6?
