How can I prevent inventory collection or discovery from timing out?
If device inventory collection or discovery is being performed over a slow network connection, or if the devices are unusually slow in responding to SNMP or HTTP requests, you can change the ivr.properties file to prevent Operations Manager from timing out during discovery or inventory collection. The file is located in the NMSROOT/conf/ivr folder. To increase the time allocated for discovery or inventory collection, change the property messageFactor:6 to messageFactor:10. The higher the number, the longer Operations Manager waits before timing out. You can also increase the SNMP timeout (Devices > Device Management > Inventory Collection > SNMP Configuration).
