Hi All

I have been playing with the latest release of the client and sever over the past few days and have managed to get everything working (and some cool new bits) apart from the log file monitoring. I can get it so it shows the log file on the hobbit display/web but I cannot get it to search for anything and cause a status change

I have this in client-local.cfg
[db184.corporatesystems.com.au]
file:/usr/bin/make
file:/usr/bin/gcc
log:/var/log/messages:10240

And then this in the hobbit-clients.cfg

HOST=db184.corporatesystems.com.au
   PORT "LOCAL=%([.:]10042)" state=LISTEN TEXT=WEBMIN
   PORT "LOCAL=%([.:]22)" state=LISTEN TEXT=SSH
   PORT "LOCAL=%([.:]50000)" state=LISTEN TEXT=DB2
   PROC cron 1 -1 yellow
   FILE /usr/bin/make MODE=644
   FILE /usr/bin/gcc MODE=644
   LOG /var/log/messages verify COLOR=yellow

This is a few lines from the log

[root (at) db184 root]# cat /var/log/messages |grep Verify
Jun 5 03:00:04 db184 kernel: 3w-xxxx: scsi2: AEN: INFO: Verify started: Unit #0.
Jun 5 05:41:17 db184 kernel: 3w-xxxx: scsi2: AEN: INFO: Verify complete: Unit #0.
Jun 8 15:30:27 db184 kernel: 3w-xxxx: scsi2: AEN: INFO: Verify started: Unit #0.
Jun 8 15:30:29 db184 3w-xxxx[29749]: INFORMATION: Verify started on unit 0 on controller ID:2. (0x29)

I have tried regex entries and all sorts and still cant get anything out of it and I'm going crazy. 'verify' is part of a string that comes out when you start a verify on the 3ware raid controller in that server. The man page says the matching string is case insensitive but I have tried it with proper case also.

Can someone please help point out the stupid thing I'm doing as I'm sure the log file monitoring does actually work :)

Cheers

Extract of hobbit-clients.cfg man page:

     Note that Hobbit defaults to  case-
     insensitive  pattern matching; if that is not what you want,
     put "(?-i)" between the "%" and the  regular  expression  to
     turn  this off.


Try this:

LOG /var/log/messages %(?-i)verify COLOR=yellow

I had already tried that as per the man page and I also tried against a lower case string such as 'session' which gets written everytime you open an ssh connection and even that didnt do anything.

Also something that I havent found clear is how do you define multiple strings ? On the same line with spaces or one LOG line per string ?

You do have to be very careful, if the log file is logging A LOT of messages. Specifically more than the 10240 bytes you are asking for. In other words, if the log file grows by more than 10240 bytes every five minutes you will lose part of the log file.


Your config entries look OK to me, those are both on the hobbit server right? Do you see the 'Verify' string in the output on the web page, Client data link?

No chance of the log growing that much it only spits out about 2 lines to the messages log per day.

And yes I have defined the log in the local.cfg and also the log and the string to match in the hobbit-clients.cfg under the appropriate host definition.
I can see the parts of the log coming out in the client data link, and also it appears on the web page itself where it says Full Log /var/log/messages

I might try do some testing on a different client and see if I get anything different.
