Hi. I've recently witnessed a phenomenon of a/m stats remaining constant for a quite a lengthy duration. The related OIDs are: ifTable & systemStats. While monitoring those OIDs, I've also monitored those stats via alternative pathways (CPU via 'top', if stats via kernel statistics in /sys/class/net), to assert that indeed the actual data is being modified.
Apparently the host's clock has been updated w/o restarting snmpd. I've learned this from looking at the PID file: ~ # stat /var/run/snmpd.pid File: `/var/run/snmpd.pid' Size: 5 Blocks: 8 IO Block: 4096 regular file Device: 803h/2051d Inode: 546305 Links: 1 Access: (0600/-rw-------) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2010-05-08 11:20:42.308213175 +0000 Modify: 2010-05-08 11:20:42.308213175 +0000 Change: 2010-05-08 11:20:42.308213175 +0000 The skewed times are according to the pre-adjusted clock. Once I restarted snmpd, a/m objects went back to being updated. I'm wondering, though, whether I should generate a dependency between the ntpd & snmpd services. Arguably, a shift in machine clock has profound affects on snmpd. Any thoughts?
