Hi everybody
i'm just trying to figure out how to fix this:

Our Netapp Storage is not reliable on SNMP, missing lots of checks due to timeout (already engaged netapp's support, but with very low expectations on their fixing it
The timeout reports UNKNOWN STATE (as defined by service_check_timeout_state=u) and when a volume is already in HARD WARNING / CRITICAL STATE, this happened to be a HARD STATE CHANGE and a notification is correctly sent out. Howerver, this happens constantly messing up good notifications
Would be nice if timeouts < N do not generate a HARD STATE CHANGE, while timeouts > N would mean something more serious and it's fine if it pops a notification.

I don't think this is recognizable as flapping...is it?
Any idea?

Thanks

What plugin are you using? Is it possible to extend the timeout via this plugin?

You could increase retry amounts. Otherwise you may want to custom script a plugin to be a bit more forgiving with the timeouts.

I'm using check_naf.py by team(ix)

define service {
service_description check_manu_test
check_command check_naf_volume_manu!/vol/volmanutest!80%!90%
host_name NETAPPSAN
check_period 24x7
notification_period 24x7
contact_groups +admins-email
max_check_attempts 5
check_interval 5
retry_interval 1
notification_interval 0
notification_options w,c,r,f,s
notifications_enabled 1
event_handler_enabled 0
}




1) modify the plugin? I'll go on studying python...

2) increase timeout (now: service_check_timeout=60), even if when the storage doesn't answer SNMP when it is busy, and usually it stays busy for much longer. What a fair timeout could be? 5 / 10 minutes? Isn't it to much?

3) retry amounts : is it the retry_interval parameter?

Thanks!!!

You should be able to run the plugin with a "-h" flag from the command line to see usage options, plugins which follow our guidelines have a timeout flag you can add to the command to increase it's timeout integer.

### ./check_naf.py -h
Usage: check_naf.py [options]

Monitoring NetApp(tm) FAS systems

Options:
--version show program's version number and exit
-h, --help show this help message and exit
-H HOST Host to check
-P 1 SNMP protocol version
-C public SNMP v1/v2c community OR SNMP v3 quadruple
--snmpcmdlinepath=/usr/bin/
Path to "snmpget" and "snmpwalk"
--nonetsnmp Do not use NET-SNMP python bindings
--separator=, Separator for check/target/warn/crit
--subseparator=+ Separator for multiple checks or targets
--check=CHECK OBSOLETE - use new syntax!
--target=TARGET OBSOLETE - use new syntax!
-w WARN OBSOLETE - use new syntax!
-c CRIT OBSOLETE - use new syntax!
--snmpwalk=SNMPWALKOID
DEBUG: "list" OIDs or SNMPWALK it
-v, --verbose Verbosity, more for more
### ./check_naf.py --version
0.9


I don't see the timeout flag
I checked and it looks like the last version, there's no newer.

maybe you know some other netapp filer plugins i could try?

There are a few here:

Thanks.
I’ll try http://exchange.nagios.org/directory/Pl ... NG/details (the best reviewed) to exclude this is a plugin problem.

Looking further, is there any way to force nagios to ignore timeouts for specified services?

Well, if the service has a timeout function set, you could remove it. Otherwise the nagios.cfg file houses a global timeout rate. This is changeable but is a nice precaution against runaway checks.
