Hey folks,

 

Looks like I goofed up the github URL, so you're not going to see updates to the SNMP package unless you uninstall and reinstall. Sorry about that. FYI the only update in a while has been the fix for this problem.

Hi Guys,

 

Not sure if any of you will be able to help me, i can't get my head around observium, do i install it as bridge or host?

if i go bridge i can access observium but can't add any devices, and if i go host it has a cry about sql, i believe because i am already running mysql on port 3306

 

Ideas?

 

Cheers,

Hi coppit,

is there any chance to add the drive temperatures to the MIBs the same way, you added the unraid drives?

 

hmm i'm past that part and i don't wanna delete unraid but i will if you can't get it working. try this first, it's just

 

hostname = tower

protocol version = v2c

port = 161

snmp community = public

 

pretty sure everything else was blank/default.

 

I can't seem to add unRaid as a device. Using those settings I get:

 

Adding host Tower community public port 161

Could not resolve Tower.

Hi coppit,

is there any chance to add the drive temperatures to the MIBs the same way, you added the unraid drives?

.. and while thinking about it: It would be nice to add the up/down state also to MIBs - that would give a great historical view on the spinning status of the drives!

Is this possible?

Checked it myself - if I understand it correct, it should be possible:

See http://www.net-snmp.org/docs/man/snmpd.conf.html

So snmpd.conf has to be extended by Agent functionality.

Current content of /usr/local/emhttp/plugins/snmp/snmpd.conf is:

rocommunity public
syslocation Here
syscontact root@tower
disk /mnt/disk1
disk /mnt/disk2
disk /mnt/disk3
disk /mnt/disk4
disk /mnt/disk5
disk /mnt/disk6
disk /mnt/disk7
disk /mnt/disk8
disk /mnt/disk9
disk /mnt/disk10
disk /mnt/disk11
disk /mnt/disk12
disk /mnt/disk13
disk /mnt/disk14
disk /mnt/disk15
disk /mnt/disk16
disk /mnt/disk17
disk /mnt/disk18
disk /mnt/disk19
disk /mnt/disk20
disk /mnt/cache

Extended agents could be implemented like this:

Extending Agent Functionality

Arbitrary Extension Commands

Old Style

    exec [MIBOID] NAME PROG ARGS"
    sh   [MIBOID] NAME PROG ARGS"
    execfix NAME PROG ARGS"

New Style

    extend [MIBOID] NAME PROG ARGS"
    extendfix [MIBOID] NAME PROG ARGS"

So if it is possible to get the information from emhttp via perl, it should be doable, iiuc?

Sorry for another post, but continued some reading and it seems that also shell scripts are supported:

# Run a shell script containing:
#
# #!/bin/sh
# echo hello world
# echo hi there
# exit 35
#
# exec .1.3.6.1.4.1.2021.50 shelltest /bin/sh /tmp/shtest

# Other ideas:
#
# exec .1.3.6.1.4.1.2021.51 ps /bin/ps
# exec .1.3.6.1.4.1.2021.52 top /usr/local/bin/top
# exec .1.3.6.1.4.1.2021.53 mailq /usr/bin/mailq

So it shouldn't be too difficult to use the respective parts from e.g. dynamix temp plugin (shell script), that is already determining temperature and disk status and output to a MIB.

 

# Identify the drives in your array so we can test their temperature
COUNT=1
for d in $(ls /dev/[hs]d? | grep -v "$flash")
do
<------>HD[$COUNT]=$d
<------>#echo HDD=${HD[$COUNT]}><------><------><------><------><------><------><------># Uncomment for debugging
<------>COUNT=$[$COUNT+1]
done
<------>while [ $CURRENT_DRIVE -le $NUM_OF_DRIVES ]
<------>do
<------><------>SLEEPING=`hdparm -C ${HD[$CURRENT_DRIVE]} | grep -c standby`
<------><------>if [ "$SLEEPING" -eq 0 ]; then
<------><------><------>CURRENT_TEMP=`smartctl -A ${HD[$CURRENT_DRIVE]} | grep -m 1 -i Temperature_Celsius | awk '{print $10}'`
<------><------>fi
<------><------>CURRENT_DRIVE=$[$CURRENT_DRIVE+1]
<------>done

hdparm tells us, if the drive is in standby - smartctrl tells us the drive's temp.

Question: I had a look into myMain.awk code of unmenu - it also uses smartctl to gather disk temp - and also gets them when disk is spun down - iirc, this is not possible with all drives/manufacturers, but it would be nice to get temps continously :-).

I did a quick test with my drives on the command line and smartctl -A /dev/sdx does not spin up the drive and nicely reports the data...

Hope that helps?

It looks like it might be possible:

When I get some time I'll take a look.

 

Edit: Catching up on your other posts, I see that you may have found a better method that doesn't require rebuilding snmp. Thanks!

I can't seem to add unRaid as a device. Using those settings I get:

 

Adding host Tower community public port 161

Could not resolve Tower.

 

Try using the IP address instead?

You have to provide hostname which can be resolved to IP address. Resolution can happen e.g in your home router.

In other words Observium only accepts hostnames.

I gave up. Thanks for looking.

is it possible to configure snmp to not log every single connection it gets? after 10 days, the snmp log file is about 40MB...

Is there a way to test to make sure it is installed and working right? Having trouble trying to connect to observium.

 

On another computer I tried to telnet to tower on port 161 which should at least connect if the port is open but doesn't work.

 

Thanks

On installation it does a self-test. Uninstall and reinstall to double-check it.

Installed and feeding data to MRTG (old school, I know).  Now to see what OIDs are good to watch!

Hi all,

 

I've dropped the log level to "warning", and it so far hasn't put anything in my log. That should help with disk usage.

 

I've also integrated drive temperatures:

 

$ snmpwalk -v 2c localhost -c public 'NET-SNMP-EXTEND-MIB::nsExtendOutLine."disktemp"'
NET-SNMP-EXTEND-MIB::nsExtendOutLine."disktemp".1 = STRING: ST3000DM001-1ER166_W500ARQN: 31
NET-SNMP-EXTEND-MIB::nsExtendOutLine."disktemp".2 = STRING: ST3000DM001-1ER166_W500QFEF: 35
NET-SNMP-EXTEND-MIB::nsExtendOutLine."disktemp".3 = STRING: WDC_WD20EARS-00MVWB0_WD-WMAZA3285404: 36
NET-SNMP-EXTEND-MIB::nsExtendOutLine."disktemp".4 = STRING: ST2000DL003-9VT166_5YD317TZ: 37
NET-SNMP-EXTEND-MIB::nsExtendOutLine."disktemp".5 = STRING: WDC_WD20EARS-00MVWB0_WD-WMAZA3209264: 37
NET-SNMP-EXTEND-MIB::nsExtendOutLine."disktemp".6 = STRING: TOSHIBA_DT01ACA200_734L5LLKS: 42
NET-SNMP-EXTEND-MIB::nsExtendOutLine."disktemp".7 = STRING: WDC_WD20EARS-00MVWB0_WD-WMAZA2183297: 35

 

Unfortunately drive temps are like the only thing Observium doesn't handle automatically. This thread might give you some idea of how to set it up.

I've also integrated drive temperatures

 

Nice.  I just updated the plug-in, but I'm not seeing temperatures, either in your installation test, or from my SNMP monitoring server.  Here's the snippet from your installation:

Looks like snmpd is working... Output:

Doh. I forgot to install the helper script. Try version 2015.08.25. Hopefully this time the test output will show drive temps.

 

I'm not 100% sure the temps will be picked up by your monitor. If you can find any docs on what the monitor queries for, I can see about supporting it.

Hmm...  On the plus side, this plug-in architecture works great!

 

Here's the fresh output - no real change:

plugin: updated

 

unRAID can see the temps - as shown in the screen shot below.  To complicate things - My unRAID system is a virtual guest on VMware ESXi.  The disk controller is "passed through" to the VM, and is dedicated to the VM, as are all the attached disks.

 

Thanks,

Can you log into your server and run the following?

 

/usr/local/emhttp/plugins/snmp/drive_temps.sh 

 

Hi, I just did and it lists all my hard drives with a colon but no temperatures at all. Drives are all spun down though. Hope this helps, Alex. PS: I'm on the latest version of the plugin.

That worked:

Yeah, I can't always get temps if the disks are spun down.

That worked:

 

Well, is the config file updated properly?

 

$ tail -n 1 /usr/local/emhttp/plugins/snmp/snmpd.conf 
extend disktemp /usr/local/emhttp/plugins/snmp/drive_temps.sh

 

What happens if you run it manually?

 

snmpwalk -v 2c localhost -c public 'NET-SNMP-EXTEND-MIB::nsExtendOutLine."disktemp"'

 

If that works, you can try restarting snmpd:

 

bash /etc/rc.d/rc.snmpd stop
bash /etc/rc.d/rc.snmpd start
