This may be good for some operations, but if one if plotting this information in real time, 15 sec interval is useless. Although there is no configuration directive to change this at runtime, there is a way to change the value. running the following command after snmpd has started (give it 10 secs to start typically) will change the cache time for the IF-MIB and make the in/out byte count update as frequent as 1 sec. /Database/opt/x.x/packages/bin/snmpset -c write -v 1 127.0.0.1 NET-SNMP-AGENT-MIB::nsCacheTimeout.22.214.171.124.126.96.36.199 i 1 This assumes that the RW community is named “write” in the snmpd.conf I hope this helps others running net-snmp under ZeroShell Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
