Check Netapp NG

Hi,
First of all thanks for the plugins which work great.
We just have a little problem with the diskused option.
We are monitoring about 70 volumes on a fas8020 CDOT.
Sometimes, all volumes are turning red with an out of bound return code. Those false positive are resorbed with a recheck.
I tried to change the SNMP timeout session as ebardellidoxee says :

1) Manage SNMP timeout.
my ($sess, $err) = Net::SNMP->session( -hostname => $server, -version => $version, -community => $comm, -timeout=> 60);
If you don’t specify any value, the default is 5 secs and in a busy environment it misses lots of packets. You might add a flag that populate the –timeout parameter of the Net::SNMP->session

But when I change it I got a general error of this plugin.
It seems that the timeout parameter for snmp session is not good.

Did someone encounter the same problem and how to solve it ?
Thanks,
regards

The FAILEDDISK command does not work on my FAS2220, ONTAP 8.1.3. Via telnet, the disk show command says I have one failed disk, yet this check insists there are no failed disks. Manual snmpwalk on the OIDs (1.3.6.1.4.1.789.1.6.4 and below) confirms the system thinks there are no failed disks when queried via SNMP. Possibly a bug in ONTAP?

Looks promising but I have not found that it can support 64-bit values which is a must for large volumes.

Hi

Thank you very much for that plugin. It seems the best for NetApp for me.

I have only one issue: I can't get proper volume space status output.

I'm entering
./check-netapp-ng.pl -H -C fpx_snmp -T DISKUSED --vol /vol/home/

And all I get is the pipe symbol:
|

?Any clue??

We were using one of the derivatives of the original check_netapp perl scripts, and the DISKUSED was always timing out and throwing errors. Running Wireshark showed that each check was pulling down all the data from each and every volume and .snapshot. This 'Check Netapp NG' script (for the DISKUSED at least) pulls down the list of all the volumes and .snapshots, but only pulls the Total, Used, and Free of the single volume in question. All our DISKUSED checks are now working correctly!

Best of all, no more flood of false critical alerts texting my phone!

Hi Ranl,
First of all congratulations for this plugin, it works fine and it’s been really useful to me.

I replaced the previous plugin I was using (check_naf.py) with yours because it was no more reliable generating lots of false positives , however I needed to make some fix and write a new function to replicate some functionalities I loved.

I’m writing to give you a couple of hints, that might improve a little your already really good plugin.



1) Manage SNMP timeout.
my ($sess, $err) = Net::SNMP->session( -hostname => $server, -version => $version, -community => $comm, -timeout=> 60);
If you don’t specify any value, the default is 5 secs and in a busy environment it misses lots of packets. You might add a flag that populate the –timeout parameter of the Net::SNMP->session



2) Negative values when vol > 2TB
Perl’s Net::SNMP returns negative wrong values when the volume check is bigger than 2TB to fix it I needed to added the following workaround

my $snmp_netapp_volume_id_table_df_total = "$snmp_netapp_volume_id_table_df.3";
my $snmp_netapp_volume_id_table_df_total_h = "$snmp_netapp_volume_id_table_df.14";
my $snmp_netapp_volume_id_table_df_total_l = "$snmp_netapp_volume_id_table_df.15";
my $snmp_netapp_volume_id_table_df_used = "$snmp_netapp_volume_id_table_df.4";
my $snmp_netapp_volume_id_table_df_used_h = "$snmp_netapp_volume_id_table_df.16";
my $snmp_netapp_volume_id_table_df_used_l = "$snmp_netapp_volume_id_table_df.17";
my $EXP=4294967296;

…
…
…
### into the function ###

if ($total

I can able to see the results of disk used details
./check-netapp-ng.pl -H 172.16.4.16 -C public -T DISKUSED --vol /vol/vol_testlab/
OK: DISKUSED 1% | /vol/vol_testlab/= 23365520k

However i couldn't get the results for below query, correct me if im wrong.
./check-netapp-ng.pl -H 172.16.4.16 -C public -T DISKUSED --vol /vol/vol_testlab/qtree_testlab
|
NO RESULTS DISPLAYED....


I couldn't get the subfolder disk information from this plugin. let me know how to get those details..Thanks in Advance!!

If you want ot monitor your NetApp then use this. It works great on our NetApp 3170

Hi,

I am trying to configure the Shelf part of the plugin. the rest works really well.

but first problem i have come across is that i dont really understand what all the items mean.

for example this is the output from the SHELF check.

VoltOverFail ,
VoltUnderFail
TempUnderFail
PsFail ,
TempOver 1, 2, 3
ElectFail 1, 2
VoltUnderWarn
VoltOverWarn
FanFail 1, 2
TempUnderWarn
TempOverFail 3
VoltOverFail 24, 24

what do all the numbers mean next to the different parts and does anyone know why some are blank or have N/A

This worked out of the box with my NetApp FAS2040 & FAS2240 systems.

I had a bit of trouble getting the Volume Usage check to work properly, but then realised I wasn't specifying the container correctly. Below is how I got it to work in the end.

./check-netapp-ng.pl -H -C -T DISKUSED -w 80 -c 90 --vol /vol/v_datastore_vdi1/

OK: DISKUSED 41% | /vol/v_datastore_vdi1/=30458796k

Hi,

Just to tell you that is a very good perl script !
Awesome work !
I recommended !!


For others, some informations :

(Examples of my commands.cfg)
define command{
command_name check_netapp_cpu
command_line /usr/bin/perl5.8.8 $USER1$/check-netapp-ng.pl -H $HOSTADDRESS$ -T CPULOAD -w 80 -c 90 -C public
}

define command{
command_name check_netapp_fan
command_line /usr/bin/perl5.8.8 $USER1$/check-netapp-ng.pl -H $HOSTADDRESS$ -T FAN -w 1 -c 3 -C public
}

and in services.cfg :


define service{
use generic-service,graphed-service
host_name machineX,machineY
service_description CPU Load
check_command check_netapp_cpu
}

define service{
use generic-service,graphed-service
host_name machineX,machineY
service_description Fan Fail
check_command check_netapp_fan
}


results :

OK: CPULOAD 1% | cpuload=1percent
OK: FAN 0 | failedfans=0


If that help someone ;)
