Re: [Nagios-users] experience with check_sasraid_megaraid for Dell PERC 4?
Wow, that changed things big time. Using snmpwalk locally this time resulted in 221 lines of output along the lines of SNMPv2-SMI::enterprises.3582.1.1.14.0 = INTEGER: -1 check_sasraid_megaraid says Megaraid OK - 2 logical disks, 6 physical drives, 1 controllers found I think I'll compare the two snmpd.conf files that I've got. Maybe learn something. Dude, you rock! Thanks again!

Well, krikey! SELinux is disabled so that isn't in play. I will get in touch with Dell, although their linux-poweredge mailing list (where I also asked the same question as here) has returned null.

Re: [Nagios-users] experience with check_sasraid_megaraid for Dell PERC 4?
Well, if I use the default snmpd.conf, I can connect to the host using snmpwalk locally and from the nagios host, but I can't see anything related to the perc array. It is this configuration that causes the perl substr error when I run check_sasraid_megaraid. Renaming percsnmpd.conf -> snmpd.conf, I can't connect to the host at all either using snmpwalk or the script. Both conf files have a line "pass .1.3.6.1.4.1.3582 /usr/sbin/percmain" as the last line of the file, but I don't understand enough about snmp (reading the docs is giving me a headache! :) to be able to connect the dots. Would you share relevant snmpd.conf info for me, James? Much thanks for your patience and advice.

Re: [Nagios-users] experience with check_sasraid_megaraid for Dell PERC 4?
Progress, of sorts. I installed nagios on another CentOS box to ensure that you and I are working from the same essential config. Had exactly the same perl errors as before. Doing some debugging of the script, it occurred to me that the first error substr outside of string at ./check_sasraid_megaraid.pl line 461. was a great big clue perhaps the script wasn't getting anything back from the percsnmp daemon on the monitored box. Since I was running snmpd using the default snmpd.conf, I figured that since I'm only going to use the percsnmpd, why not symlink percsnmpd.conf to snmpd.conf and try again. This got me much further, though still with errors: snmp error: No response from remote host 'bullwinkle' Megaraid UNKNON - could not retrieve snmp table blah blah OK, so I'm guessing that something is broken in my snmp config. Guess it's time to try to figure that out. RTFM, as they say! Bo jmose...@corp.xanadoo.com wrote: > Doesn't matter if you're not using the plugin within Nagios yet.

Re: [Nagios-users] experience with check_sasraid_megaraid for Dell PERC 4?
Host OS is CentOS 5.x (originally 5.2 with ongoing updates applied via yum.) Perl is default install v 5.8.8. On the Nagios box (actually a VM) I'm using Groundwork Community Edition 5.3 VM as provided by groundwork. I've not actually connected the plugin to anything Nagios yet, I'm just running it from the command line. I did have to install Net::SNMP for perl from CPAN. Hmmm, what a puzzle.

Re: [Nagios-users] experience with check_sasraid_megaraid for Dell PERC 4?
Thanks for your reply, James. Your recipe for installation was perfect. I did encounter two problems, 1 of which I solved (though I don't understand why I needed to do it.) Initially running check_sasraid_megaraid from the command line on the Nagios box to get the help output complained "Can't find utils.pm in @INC" Comparing that script against many others in the nagios/libexec directory showed that many others used utils.pm (which was also in the nagios/libexec dir), and they found it just fine. I eventually added "use lib /usr/local/groundwork/nagios/libexec" to the script and that solved that particular problem. I'm not sure why this was necessary, given that all of the scripts (that I checked, in any case), including check_sasraid_megaraid were identical in usage of utils.pm. The second is that when running ./check_sasraid_megaraid.pl -H bullwinkle -T megaraid --debug it fails: alert: CRITICAL snmp error: Requested table is empty or does not exist Megaraid UNKNOWN - could not retrieve snmp table .1.3.6.1.4.1.3582.1.1.2.1.3 Initially I had opened ports 161 TCP so I thought that might be the problem, but changing them to UDP only changes the speed with which I get the failure (the timeout was operative before). I've checked that both percsnmpd and snmpd are running and snmpd.conf has the appropriate entry. Do you have other hints that may help me? Thanks again.

Re: [Nagios-users] experience with check_sasraid_megaraid for Dell PERC4?
Thanks for your quick reply, Seth. I did look at this but it seems that it requires OpenManage to be installed on the monitored server. Is that right? That gives me some concern over performance - I've heard (but have no experience with) that OM is something of a resource hog - java based? Our servers are VM hosts for a variety of other things and I'm reluctant to add yet more load for the simple need to check that status of the RAID arrays. I appreciate your insight.

[Nagios-users] experience with check_sasraid_megaraid for Dell PERC 4?
Hi all. We've got two dell servers with PERC4 controllers running CentOS that nagios is monitoring quite nicely with the exception of the raid arrays. Is there anyone that has experience with check_sasraid_megaraid as found here: http://www.nagiosexchange.org/cgi-bin/page.cgi?g=1474.html;d=1 Advice, an overview, or a recipe would be very helpful!
