I'm currently evaluating Zenoss for use in an enterprise environment and appear to be having a problem monitoring OS processes - they are always shown as "up" even if I kill the process. Here's the setup:
Zenoss Server: # cat /etc/issue |head -1 CentOS release 5 (Final) # uname -r 2.6.18-53.1.21.el5 # rpm -qa |egrep '^python-[0-9]|^net-snmp-[0-9]|^zenoss-[0-9]' net-snmp-5.3.1-19.el5_1.4 zenoss-2.2.0-0.el5 python-2.4.3-19.el5 Remote server being monitored: # cat /etc/issue |head -1 Red Hat Enterprise Linux AS release 4 (Nahant Update 6) # uname -r 2.6.9-34.ELsmp # rpm -qa |egrep 'net-snmp-[0-9]' net-snmp-5.1.2-11.el4_6.11.2 Steps to reproduce (with a fresh install and following section 11.3.1 of the admin guide): - Create a new process to monitor in Zenoss (Processes -> Add Process -> enter regex [e.g: procXYZ] -> OK). - Check that the server is running 1 instance of procXYZ with ps. Also check the you can grep for procXYZ in the snmpwalk from the monitoring server. - Add the device running procXYZ (Add device -> Set device name to remote hostname, Set device class to /server/linux) -> Add Device - View the OS Processes of the new device to make sure that procXYZ was found through snmp and is listed under OS Processes. (Device list -> hostname -> OS). - Kill procXYZ on the remote server (and wait...). - grep for procXYZ in ps on the remote host and snmpwalk from the zenoss host to confirm it's not running. -! Even though the process isn't running or seen through snmp, Zenoss still shows the state as "up" with a green light. You can also lock the process from deletion, remodel the device and the process is still "up" - however, if you unlock the process again and remodel the device the process will disappear from the OS Processes list.
