I find it hard to believe that this poses a problem for most people these days. The following is taken from a 1950 with RHEL5 and OMSA 5.5.0, that has been up for 95 days, and runs various omreport commands (via a Nagios plugin) every ~5 mins: # ps -eo pid,cputime,rss,size,args | egrep PID\|dell | grep -v egrep PID TIME RSS SZ COMMAND 5349 00:00:02 2224 102728 /etc/delloma.d/oma/bin/dsm_om_shrsvc32d 5798 00:31:13 10300 171868 /opt/dell/srvadmin/dataeng/bin/dsm_sa_datamgr32d 6142 00:01:25 3060 22156 /opt/dell/srvadmin/dataeng/bin/dsm_sa_eventmgr32d 6160 00:00:00 2340 136676 /opt/dell/srvadmin/dataeng/bin/dsm_sa_datamgr32d 6176 00:15:21 3696 52840 /opt/dell/srvadmin/dataeng/bin/dsm_sa_snmp32d Neither the processing nor the memory usage seems very alarming to me. This is not a scientific test by any means, it is just a random example from a random host. However, I can certainly see that there exist special cases where you don't want to run OMSA in order to save processing power and/or memory, but not in the general case. To me, the benefits from running OMSA outweights the disadvantages. You'll have a certified tool from Dell for monitoring and managing your servers. If OMSA reports that something is wrong, Dell support will take it seriously. And OMSA lets you monitor much more than just the status of your hardware RAID. > It look me about half a day of tinkering around to get Nagios set up and > monitoring a 2950, 1950, two 2950s, two 2650s, and a 2550 - including > RAID status of PERC5, 4, and 3 on those systems. > > Once the initial install is done, it's easy (as in less than 5 mins > setup) to monitor additional systems. > > I posted notes here: > http://stevejenkins.com/blog/2009/12/helpful-links-for-setting-up-nagios > -and-nrpe-on-rhel-5-and-centos-5/ If you had been using OMSA, you would have one tool to monitor and manage your hardware RAID (and also other aspects of the servers), and one Nagios plugin to rule them all ;) PS. The 2550 can't run any modern OMSA versions, so it's pretty much a lost case in that respect. Cheers, -- Trond H.
