You are correct in that it has nothing to do with AgentX. Our subagent collects data across a slow async bus, so the snmpd program sometimes times out the subagent. The original code always shuts down the subagent after 3 timed out AgentX packets (or whatever AgentxSubagmentMaxTimeouts was set to in /etc/snmpd.conf). Our modified code lets us disable this "feature" by setting AgentxSubagentMaxTimeouts and AgentxSubagentMaxParseErrors to zero. > > Do you monitor the UCD-SNMP work (an off-shoot from an older > CMU-SNMP release)?

We were not aware of the UCD package when we started working with the CMU package. We were also drawn to the CMU package because of earlier experience with the CMU SNMP package, which we are also using. One thing that the AgentX package needs is a thoroughly cleaned and updated documentation package. There are comments in the release notes that say things like: * Set is not supported * TCP is not supported * Getbulk is not supported >From what we have seen all of these features are supported by >the current version of CMU AgentX. It appears to be complete. -- Daris A Nevil Simple Network Magic Corporation 401 Kentucky Lane McKinney, TX 75069 214-793-7757 dnevil@snmc.com www.snmc.com quickstack.com qslinux.org
