Synology status

It works perfectly!! Thank you a lot!

I suggest to change snmpwalk to snmpbulkwalk in script. An execution of the script will be a much faster.

Not sure if this is still any use to anyone but I fixed the missing volume disk space bug by removing a $ symbol from line 317.

Original Line:

storageID[$i]=$(echo "$syno_diskspace" | grep "= "?/${storageName[$i]}$"?" | cut -d "=" -f1 | rev | cut -d "." -f1 | rev)

Replaced with:

storageID[$i]=$(echo "$syno_diskspace" | grep "= "?/${storageName[$i]}"?" | cut -d "=" -f1 | rev | cut -d "." -f1 | rev)

I am not sure if this will break anything else but it seems to be doing what I need it to now.

For anybody else who has a problem with the correct volume usage reporting, open the script and replace the line 317:

storageID[$i]=$(echo "$syno_diskspace" | grep "= "?/${storageName[$i]}$"?" | cut -d "=" -f1 | rev | cut -d "." -f1 | rev)

with this:

storageID[$i]=$(echo "$syno_diskspace" | grep "= "/${storageName[$i]}"" | cut -d "=" -f1 | rev | cut -d "." -f1 | rev)

and you should now get the correct volume usage (in percent) and the correct return state (depending on your -w and -c parameters).

Volume free space is not working. Status is always Normal. We are using this call:
check_snmp_synology -u my_user -p my_pass -h my_host -v -i

Also I tried call like this: check_snmp_synology -u my_user -p my_pass -h my_host -w 85 -c 90 -v -i

OK - Synology "RS3617xs+ is in good health

NAS storage is on 92%.

Also I check on 4 NAS different models:
Synology model: "RS3617xs+"
Synology model: "RS2414+"
Synology model: "RS2212+"
Synology model: "RS3412xs"

With 2 different DSM:
DSM Version: "DSM 6.1-15152"
DSM Version: "DSM 6.1-15047"

Did some one find solution for this?

We've been using this for a while, but we've just noticed that the volume space doesn't seem to raise warnings (just status:Normal) :
Here's the verbose output.

According to the web interface of the device, volume on is 93% full. Any ideas?

First of all, fantastic plugin. Very extensive.

However I found an issue with it. When polling a device running DSM 6.1, it returns integer expression expected.
Breaking the script down, the syno variable isn't populated.

Basically, snmpget times out. This appears to be due to amount of OIDs I'm querying. There is 12 disks in the system so there is around 50+ oids. I kept rerunning snmpget, removing a oid until it returned data and it was around 42.

Using Ubuntu 16.04, snmpget 5.7.2

Problems are fixed fast.

Hello!

I have some problems with this script, it seems something it's wrong, shows me the advise: "(No output on stdout) stderr: /usr/local/nagios/libexec/check_snmp_synology: line 323: 53"

What's wrong?

Thanks!!!

When i use the script with your command and snmpv3 and my DS411 with DSM 6.0.2 there comes the following error:
"CRITICAL - Problem with SNMP request"

try many things, but i think its a bug in your check_snmp_synology.

And yes, i use your newest version.

Hi,

is there any way to change the Port from 161 to another one?

Regards.

The plugin works great!

I had some requirements which the plugin didn't meet. Therefore, I have added some minor improvements such as separated command line options for DSM Update and enable performance data, etc.

The author didn't respond to my mail. Therefore, I have published my version on GitHub, see: https://github.com/exensio/synology-nagios-plugin

Thank you for this plugin ;)

I modify it in order to ignore DSM updates. It works perfectly.

These are the lines for add option -I to ignore DSM updates :
...
case $DSMUpgradeAvailable in
"1") DSMUpgradeAvailable="Available"; healthWarningStatus=1; updateMessage="DSM update available";;
"2") DSMUpgradeAvailable="Unavailable"; healthWarningStatus=0; updateMessage="Update unavailable";;
"3") DSMUpgradeAvailable="Connecting"; healthWarningStatus=0; updateMessage="Update in progress";;
"4") DSMUpgradeAvailable="Disconnected"; healthWarningStatus=1; updateMessage="DSM Update Disconnected";;
"5") DSMUpgradeAvailable="Others"; healthWarningStatus=1; updateMessage="Check DSM Update";;
esac

if [ "$ignoreUpdate" = "yes" ] ; then
healthWarningStatus=0;
healthString="$healthString, Info : $updateMessage";
else
healthString="$healthString, $updateMessage";
fi
...

and on the last lines, I modify the output for Ok status :
...
if [ "$healthCriticalStatus" = "0" ] && [ "$healthWarningStatus" = "0" ] ; then
echo "OK - $healthString Appliance is in good health"
exit 0
fi
...

Hello,
Your plugin works rather fine but I have a problem: when I mount an USB drive. The USB drive is mounted in the /volume1/usbdrive and the script fails.

We have a recurring warning from your plugin saying that DSM update is disconnected. I think that's because Synology has its servers down. People can have the Syno out of network so I think it will be nice to be able to disable this warning.

Another request: will it be possible to only select some tests? For example I will be interested in no dsm update tests or different volumes warning/critical levels...

Thank you for the plugin

nice plugin, monitoring two RS3412, until today without problems. today added another volume (the 10th) and script says now:

tried to find on myself, but as not a programer, no chance.. :) any help very appreciated,

Very strange value for temperature:
Synology model: "RS814"
Synology s/n: "14A0LZN498800"
DSM Version: "DSM 5.1-5022"
DSM update: Unavailable
System Status: Normal

CPU Fan Status: Normal
Number of disks: 4
"Disk 1" (model: "WD40EFRX-68WT0N0 ") status:Normal temperature:39
"Disk 2" (model: "WD40EFRX-68WT0N0 ") status:Normal temperature:40
"Disk 3" (model: "WD40EFRX-68WT0N0 ") status:Normal temperature:40
"Disk 4" (model: "WD40EFRX-68WT0N0 ") status:Normal temperature:38
Number of RAID volume: 1
"Volume 1" status:Normal 40% used
What is the difference with disk values?

I can do a SNMP walk but I always get the next error:
CRITICAL - Problem with SNMP request

I already tried with different Synology's.

Hello,

Im sorry I am a very beginner in nagios.
I paste your script into /usr/local/nagios/libexec but when I execute ./check_snmp_synology -h myip I got

-bash: ./check_snmp_synology: No files or folders of this type

Could you please help me ?

Hello Jan,

I have the same problem. My Synology displays: WARNING - Synology "RS2414rp+" (s/n: "XXXXXXXXXX", "DSM 5.1-5022") needs to be updated.

Could you please explain to me, how do you have solved the problem ?
What do you have change between line 119 to 123 ?

Thanks for your answer.

Hello, great usefull plugin...

there is perhabs a bug.

for the parameter OID_upgradeAvailable set you between line 119 to 123 all status of the parameter healthStatus on 3. This give all time a warning to do updates.

I changed in a other version for me that only by the status updates available the warning comes to do the updates.
