Issue/Introduction

Cannot perform any discovery of snmp devices in USM, although the snmp communication string given by device is already successfully tested by 3rd party MIB Browser 

Also can create profile manually from snmpcollector probe, but if we create profile manually without discovering the device in USM the device will not be listed in UIM inventory and will not generate any alarm.

 

 

Environment

Release : 9.2.0

Component : UIM - DISCOVERY

Resolution

Note that having the java memory too low for discovery_server probe can cause this error and other issues such as:

- discovery or node count inaccuracy in USM
- discovery _server slowness / performance issues

Hold down the SHIFT key then rt-click to select Raw Configure of discovery_server probe

Select startup->opt section.

See startup->options java min and max. Set them to at least 2048 and 4096 respectively 

<startup>
<opt>
java_mem_init = -Xms2048m
java_mem_max = -Xmx4096m
java_opts = -server -XX:ErrorFile=./hs_err_pid.log
</opt>
</startup>

 

Then click ok.

Cold start the discovery_server probe:
Deactivate, then Activate it
