Hi,

I'm trying to get the general temperature in this scripts.
This returns value: 0

I'm running domoticz on a ds214se. Is there an issue with the oid?



# Temperature NAS
NAS_TEMP=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.4.1.6574.1.2`
echo "NAS_TEMP:" $nastemp

# Send data
echo "Sending data to device#:" $NAS_TEMP_IDX
curl -s -i -H "Accept: application/json" "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$NAS_TEMP_IDX&nvalue=0&svalue=$nastemp"
echo "Data sent"

I am running DSM 6.2 and it works.
To get temperatures from harddisks use: 1.3.6.1.4.1.6574.2.1.1.6
You will get the temperature from every harddisk as 1.3.6.1.4.1.6574.2.1.1.6.0 1.3.6.1.4.1.6574.2.1.1.6.1 etc....

NAS_TEMP=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.4.1.6574.1.2`
echo "NAS_TEMP:" $nastemp

Wrong variable use should be echo "NAS Temp: "$NAS_TEMP Same for the curl command

I only have issues with The HD temps. Only the general temp is returning blank.

The variable change did the job! Thanks

Another question:

I've added the FAN status to my script.
The data is 1 = ok 2 = not ok (From the MIB documentation)

I've added a virtual sensor, type text. it is updates nicely. But a sensor of type text is a bit ugly in the web gui.

2 questions: 1. is it possible to use a different type of sensor? Or, is it possible to use like conditional formatting. When 1 is returned, a green color, when 2 is returned, a red color.

You could use a Type General with Subtype Alert.

I'm trying to add it too, and send it to an ' Alert Sensor" but I can't seem to get it to work. This is what I have in my script:

Code: Select all

 # Fan alert
        FANUnit=`snmpget -v 2c -c $PASSWORD -O qv $NASIP  1.3.6.1.4.1.6574.1.4.1`
        # Send data
        curl -s -i -H "Accept: application/json" "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$NAS_FAN_ALERT&nvalue=$FANUnit&svalue=FAN"
Any thoughts?

I've got it working with:

FAN_STATUS=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.4.1.6574.1.4.1`
echo "FAN_STATUS:" $FAN_STATUS

# Send data

Thanks!
Any idea what the syntax should be? If it is 1, it should be green, if it is 2 it should be red..

I use this code to update the sensor:

curl -s -i -H "Accept: application/json" "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$NAS_FAN_STAT_IDX&nvalue=0&svalue=$FAN_STATUS"
echo "Data sent"

Fixed it :-)

# Fan status
FAN_STATUS=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.4.1.6574.1.4.1`
echo "FAN_STATUS:" $FAN_STATUS
if expr $FAN_STATUS =<> "1" ; then
# Send data
echo "Sending data to device#:" $NAS_FAN_STAT_IDX
curl -s -i -H "Accept: application/json" "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$NAS_FAN_STAT_IDX&nvalue=4&svalue=$FAN_STATUS"
echo "Data sent"
else

# Send data
echo "Sending data to device#:" $NAS_FAN_STAT_IDX
curl -s -i -H "Accept: application/json" "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$NAS_FAN_STAT_IDX&nvalue=1&svalue=$FAN_STATUS"
echo "Data sent"
fi

mmm.... i'm getting this error after I followed every step in the tutorial:

Code: Select all

./nas.sh: line 125: unexpected EOF while looking for matching `"'
./nas.sh: line 128: syntax error: unexpected end of file
Any ideas?

I modified the code because some items where no longer working with DSM7.0.
In addition to that I decided I wanted to have the UPS data in Domoticz.

So I have added that too.

I use a cheap APC ups type CS350 which is connected to my nas via a usb cable.

My Domoticz system runs of the same UPS, so it is nice to know when a shutdown is going to happen.
(Now a Raspberry Pi 3B+ with an SSD, will become a NUC with an Intel J4105 Celeron.)

Modified the crontab entry, otherwise the script would not run completely (replacing spaces in a string would not work) from cron.
The /bin/bash entry is new here:

Code: Select all

*/5 * * * * /bin/bash /home/pi/domoticz/scripts/nas.sh (= every 5 minutes)
And here the code of nas.sh after modification.
The memory percentage calculation is modified to suit the amount of RAM in my nas. (6144)
I have a DS218+ with 6Gb of RAM installed.

Code: Select all

For what purpose do you use 'UPSmanufacturer' and UPSmodel in Domoticz? Does that change overtime?

You are right, those (manufacturer and model) serve no purpose at all.

Looking back at it, the only thing the ups data provides for me is info in the Domoticz screen.
For switching off the server when the ups shuts down I use nut.

Could have used nut to get the ups info in Domoticz as well.

This setup works fairly well and many of the tips written in the forum are useful. However, the disk temperatures are oscillating between 0 and 31ºC for some reason

When pinging the ip-adres I get an answer within about .420 ms

Besides that I get an error message :
line 44: ( - ) * / 1024 / 1024 / 1024: syntax error: operand expected (error token is ") * / 1024 / 1024 / 1024")
But that can be caused by the time outs ?

The script in line 43 and 44 is :

Code: Select all

 HDUsed=`snmpget -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.2.1.25.2.3.1.6.41`  # Change OID to .38 on DSM 5.1 or .41 on DSM 6.0+
        HDFree=$((($HDTotal - $HDUsed) * $HDUnit / 1024 / 1024 / 1024))
I can't see anything wrong, the only thing I changes is .36 to .41
I have a synology 213J running on DSM 6.0+

NB: When running a single command like :
HDUsed=`snmpget -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.2.1.25.2.3.1.6.41`
I sometimes get a result but not often (time out)
My issue is exactly the same as yours. I've changed my cronjob to output the log

Code: Select all

*/5 * * * * /home/pi/domoticz/scripts/nas.sh 1> /dev/null 2> /home/pi/some_job.err
and every 25 minutes or so the NAS makes some unusual noise, the temperature values return zero, and the contents of the some_job.err file becomes

Code: Select all

Timeout: No Response from 192.168.1.5
Timeout: No Response from 192.168.1.5
Timeout: No Response from 192.168.1.5
Timeout: No Response from 192.168.1.5
/home/pi/domoticz/scripts/nas.sh: line 44: ( - 201822598) *  / 1024 / 1024 / 1024: syntax error: operand expected (error token is "/ 1024 / 1024 / 1024")
NOTE: the code runs fine by hand and most of times. It is an occasional, but rather predictable (every 25 minutes) event, so maybe the way to address this is with a conditional statement? I've also run some tests and the timelapse of pinging does not give it away either: it is fairly constant at 600ms.
My DSM is version 7.2 and the nas.sh code that I'm using is

I've made a few extra tests and based on this webpage
https://www.baeldung.com/linux/snmpwalk ... out-values
one can set timeout values to improve the success rate. After a few tests I was able to avoid any timeout errors, by setting the interval at 5 seconds with 3 retries. However, the disk temperature values still return zero and the NAS does some clicking noise at every 25 minutes. If I comment out the snmpwalk commands for temperature this does not happen anymore, and I've confirmed that it happens for any of my two disks. I've checked that my commands are correct using

Code: Select all

snmpwalk -v 2c -c"mypassword" 192.168.1.5 1.3.6.1.4.1.6574.2.1.1.6
which returns

Code: Select all

SYNOLOGY-DISK-MIB::diskTemperature.0 = INTEGER: 30
SYNOLOGY-DISK-MIB::diskTemperature.1 = INTEGER: 31
and so I am not sure what else to do...(head scratching). There is a possibly related post in synology's forum

Hi, I used the monitor script for years to monitor my NAS disk usage, but I recently upgraded to DSM 7.1.1 and now it doesn't work any more.

Does anyone know the correct OID for DSM 7.1.1?

Code: Select all

       # Free space volume in Go
       HDUnit=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.2.1.25.2.3.1.4.55`  # Change OID to .38 on DSM 5.1, .41 on DSM 6.0, 42 on DSM 6.1, 44 for DSM 6.2.3
       HDTotal=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.2.1.25.2.3.1.5.55` # Change OID to .38 on DSM 5.1, .41 on DSM 6.0, 42 on DSM 6.1, 44 for DSM 6.2.3
       HDUsed=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.2.1.25.2.3.1.6.55`  # Change OID to .38 on DSM 5.1, .41 on DSM 6.0, 42 on DSM 6.1, 44 for DSM 6.2.3
       HDFree=$((($HDTotal - $HDUsed) * $HDUnit / 1024 / 1024 / 1024))
.55 also doesn't work

Perhaps this tip will help you to find the correct OID https://domoticz.com/forum/viewtopic.ph ... 78#p279178

Thanx, found it:

Code: Select all

pi@domoticz:~/domoticz/scripts $ snmpget -c xxxxxx -v2c -O qv xxx.xxx.xxx.xxx 1.3.6.1.2.1.25.2.3.1.3.48
"/volume1"
With 48 everything works again!
