Re: [Nagios-users] check snmp logic
Do you mean you want to check the result of one OID and make that treat
another OID's values differently?
Personally if I faced that problem - I would probably code a custom check
in Bash using snmpget from snmputils that did some nested If statements, or
use Net::SNMP from Perl and check it that way. Quite simple to write a
Nagios plugin - it's all about the exit values - 0 is OK, 1 is Warning, 2
is Critical, 3 is Unknown.
You may be able to use warning states generated by the first to define a
dependency on the second but it will be complicated to change the
thresholds dynamically via that method, at best you'd be able to suppress a
warning or other state from the 2nd but you couldn't have differential
thresholds between the two states of the first service without some work or
hackery (e.g. having an event trigger fire off that changes the
configuration file and reloads nagios)
I would just code it into a plugin (assuming you or someone on your team
can code)
Something like this perl pseudo code...
use Net::SNMP;
$snmp = Net::SNMP->session(-hostname => $ipaddress, -community => "public",
-version => 'snmpv2c');
@oids = qw/1.2.3.4 1.2.3.5/;
$res = $snmp->get_request(-varbindlist => \@oids);
unless(defined($res))
{
print "UNKNOWN - no response\n";
exit(3);
}
$firstoidval = $res->{$oids[0]};
$secondoidval = $res->{$oids[1]};
if ($firstoidval == 1) #running?
{
if ($secondoidval > 50) { print "CRITICAL - running and temp above
critical threshold"; exit(2); }
if ($secondoidval > 45) { print "WARNING"; exit(1); }
else { print "OK"; exit(0): }
}
elsif ($firstoidval == 0) #notrunning?
{
if ($secondoidval > 40) { print "CRITICAL"; exit(2); }
if ($secondoidval > 35) { print "WARNING"; exit(1); }
else { print "OK"; exit(0): }
}
Logic probably differs a bit, but you get the gist...

Re: [Nagios-users] Return code of 127 is out of bounds - plugin may be missing error for check_memory.py
Try running the check as the nagios user and see what happens. I ran into this problem also when I was using a very large number of services (3500+) in a single service group, which I fixed by turning off environment macros On Mon, Apr 15, 2013 at 8:43 PM, nag ios wrote: > Hi, > > i have a problem while using check_memory.py plugin its poping up error as > below. > > (Return code of 127 is out of bounds - plugin may be missing) > > permissions for the plugin as root and root for owner , group owner. > > Please help me out > > > -- > Precog is a next-generation analytics platform capable of advanced > analytics on semi-structured data.

Re: [Nagios-users] Different notifications for different services
Just assign different contacts or contactgroups to the different hosts and services, then set up different notification commands on those contacts On Mar 29, 2013 2:04 AM, "Alex Trifonov" wrote: -- Own the Future-Intel(R) Level Up Game Demo Contest 2013 Rise to greatness in Intel's independent game demo contest.

[Nagios-users] Host List Sorting issues - WAN links with lots of hosts
Hi All, Long time user, first time poster on the list. I have a fairly large distributed monitoring setup currently in pilot that's monitoring a variety of devices at remote branch sites. The hostnames at all these sites are very similar since the naming standard includes the branch ID at the start of the hostname. What we are seeing is Nagios' scheduler is using a sorted list to drive the host check scheduling decisions, which means all or the majority of devices at a particular site are being checked at once. With all those ICMP packets going down a long thin WAN link that may be close to 100% utilisation, we are seeing all the devices at the site go down at once, then come back up as soon as the next check is run in a more staggered manner. I have checked the source code and the host list Nagios uses is sorted after reading the config files and the scheduler routine simply walks the linked list of hosts, and adds them into the schedule. My ideas to solve it... - Modify check_icmp with a wrapper script or similar that adds a random delay to the ping check to avoid the mass of packets (OK but will still lead to events where all the randomness adds up) - Modify the Nagios source code and recompile to remove the sorting of host lists (suboptimal) - Increase the thresholds for ping timeouts etc (doesn't really let us track latency of each site as it's then affected by the ping grouping) Any ideas from the community that'd be useful?
