F5 SNMP OID Value
Hi, I am currently configuring SNMP V3 on my F5 LTM and want to monitor it using SolarWinds. -Currently from configuration utility i have configured a community as public (don't know if it is recommended) and default. -Then I have configured SNMP v3 agent and defined authentication and hostname and their respective passwords and send this to SolarWinds team. -I verified all the MIB files reside in /usr/share/snmp/mibs/ directory -I don't know how to specify OID value ? Can anyone please help what else can i do to configure SNMP correctly and how can I get OID value ? Thanks
snmp-check external monitor
Problem this snippet solves: This external monitor script runs an snmpget to pool members and marks the members up or down based upon the result. Specifically created for this GTM/APM use case, but can be modified as needed. How to use this snippet: copy the contents of this file into /config/monitors/snmp-check, and then in the external monitor configuration, reference the monitor and provide the following variable key/value pairs: result=<result> community=<community> OID=<oid> Code : #!/bin/sh # # (c) Copyright 1996-2005 F5 Networks, Inc. # # This software is confidential and may contain trade secrets that are the # property of F5 Networks, Inc.

SNMP - No Such Object available on this agent at this OID
Supp! I need this disk space alert it keeps failing.. Also, is there any OID to track the % used space, as in var percentage in use? [root@bigip1:Active:Standalone] config # snmpwalk -v 2c -c public localhost .1.3.6.1.4.1.3375.2.4.0.25 F5-BIGIP-COMMON-MIB::bigipDiskPartitionWarn = No Such Object available on this agent at this OID [root@bigip1:Active:Standalone] config # This is insanity, why won't this work, looks like all oids are just wrong..
SNMP timeout even through localhost
Hello Devs! I have a 5250 appliance that for some odd reason is not responding to SNMP! Current config is as follows: root@(bigip1)(cfg-sync Standalone)(Active)(/Common)(tmos) list sys snmp sys snmp { agent-addresses { tcp6:161 udp6:161 } allowed-addresses { 127. 10.10.10.182 } communities { test { community-name mycommunity source default } } disk-monitors { root { minspace 2000 path / } var { minspace 10000 path /var } } process-monitors { bigd { process bigd } chmand { process chmand } httpd { max-processes infinity process httpd } mcpd { process mcpd } sod { process sod } tmm { max-processes infinity process tmm } } sys-contact nobody sys-location someplace } root@(bigip1)(cfg-sync Standalone)(Active)(/Common)(tmos) When the host tryes to do a snmp get, it timeouts. I can see the get coming in but big-ip never answers it...

(Config search path: /usr/share/snmp) It's unlikely this agent can serve any useful purpose in this state. Run "snmpconf -g basic_setup" to help you configure the snmpd.conf file for this agent. Any ideas of what to do next? I really don't want to reload this box since it is not part of a cluster... Thanks! Rafael
Polling Pool Member Status via SNMP?
Hello... I've been working thru the documentation at https://devcentral.f5.com/questions/bigip-snmp-pool-members-info. I can successfully query the pool member status OIDs after using snmptranslate to find them. However if I disable a pool member from the UI the result of the query of the pool member status OID always seems to be "4" even though the pool member shows 'Available (Disabled) - Pool member is available, user disabled' in the UI. I am assuming the query result should return "25" if the pool member has been manually disabled? What should be the correct value returned from the pool member monitor state if the pool member has been manually disabled in the UI? Thanks!
