Server Loaded and Ready

[Eric]

OK This weekend our TM1 server decided to freeze up. I restarted the service and waited for 35 minutes for it to be back up and running. After 35 minutes, the time it has taken to restart for about a year, the TM1 Server was still not available. Checking the server everything was running fine, but data was still loading No big deal should be up any minute.

I found myself refreshing available servers every minute for 15 more minutes!
This annoyance lead me to a question. I currently have TI processes in place to send emails if there is an error. Is there some kind of flag or trigger in TM1 or in Windows that I can leverage to send an email when the server is loaded and ready?

*After I got it up and running I found that the culprit was a new cube with all kinds of calculations and feeders.

Unfortunately, the short answer is no.

I think you'd have to monitor the % processor usage of either the tm1s.exe or tm1sd.exe process and see when it dropped to zero to determine that the server was fully loaded and ready.

Hello,

we've managed to be notified when our TM1 Server is ready by a shell script (It's on an Unix box ...) that searches the string 'TM1 Server is ready' in the tm1smsg.log file, then displays a message.

The code looks like:

Code: Select all

bReady=0
sFile=/usr/local/tm1/logdir/tm1smsg.log
while [ "$bReady" = "0" ] ; do
  # wait 1 second ...
  sleep 1

  #   extract the last line from tm1smsg.log
  #  then search 'TM1 Server is ready'
  sLine=`tail -1 $sFile | grep -i 'TM1 Server is ready' `

  # Check if the string has been found.
  # if the resulting variable (sLine) contains  'TM1 Server is ready' , the server is started.
  # else, the string should be empty ("")
  if [ "$sLine" != "" ] ; then
     # ok, line has been found.
     # the server is ready
    bReady=1
  fi
done
echo "the server is ready"

(I don't know if it can be rewritten as a windows batch file ...)

Renaud.

Mmm... fiendishly ingenious! I might see what can be done there with a little modification to a VB app that I once wrote. It was designed to check for the presence or absence of files, but also had snippets to sometimes read the contents of text files as well when it needed to. I haven't looked at it for ages.

The only problem is that I think that under Windows, that method will only work with later versions of TM1. If memory serves me correctly the earlier versions have the log files locked up tight and no outside app could access them. I seem to recall that they later changed that, but it wasn't until... 9.1? It was something that I read in the release notes, which I don't have to hand at present.

From memory, that is the case pre 9.1. I had a situation where I needed to access the tm1smsg.log and I had to stop the server and take a copy of the file in order to get a look at it outside of Server Explorer.

I second that motion. Renaud gets the award!

I have never worked with Shell Script, but now I have a reason to take a peak.
