VMWare / ESXi logging disk temperatures
Posted by  Admin on

Following on from a previous post, this details how I log my ESXi disk temperatures.

The temperatures are gathered with this script:

/vmfs/volumes/datastore2/hp/hpacucli ctrl slot=16 pd all show detail |grep "Current Temperature (C):" |awk -F ":" {'print $2'} |xargs |sed -e 's/ /,/g' > /vmfs/volumes/datastore2/hp/disk_temps.txt
cat /vmfs/volumes/datastore2/hp/disk_temps.txt | nc -w 3 <> 1025

Port 1025 was chosen at random - any unassigned port above 1024 can be used.

I have another machine on with a daemon listening on port 1025

Define this new service in /etc/services

xfer            1025/tcp

The script (daemon) on is run from xinetd.d and looks like this:

service xfer
    disable         = no
    flags           = REUSE
    socket_type     = stream
    wait            = no
    user            = root
    server          = /usr/local/bin/

Content of /usr/local/bin/

echo "$INCOMING" > /tmp/temps.txt

/tmp/temps.txt is read by another program (in my case the Eluna Graph System ) which graphs the temperatures.
