Logfile not accessible

I'm monitoring about 8 log files on a system, and on some

of them, I'm getting a "Logfile not accessible" .

 
I can login to the box as the hobbit user and cat the files out

just fine. The privileges all match up with the other logfiles that are

working just fine. Manually, I can see the files just fine.

 
How does Hobbit try to read the log files?

 
I would appreciate any suggestions.

 
Thanks.James

But, if you changed the hobbit user's group memberships since you last 
restarted the hobbit client, you would receive the new group when logging in, 
but the client would still be running without that group.

So, try restarting the client.

The group membership has always been the same.
I've never changed it, and the group membership and ownership
of the logfiles, both working and non-working are the same.

How does Hobbit look at log files? A standard Cat, Grep, Tail?

Can anyone give me a way to debug this?

Thanks.....James

what OS r u on ? could it be some ACL or SELinux policy or alike to forbid
the process/daemon to access while interactive shell is ok?

It uses Hobbit's "logfetch" utility, which basically opens the file for
reading.

Have you checked for errors in the client logs ? ~hobbit/client/logs/ on
the client system.

Henrik

Yes, I did.

I've suspended monitoring the log files with problems
for now. I'll try again later in the week. I had to
work out another monitoring problem late last night.
I'll send a email on the problem because I need assistance.

Thanks....James

Greetings everybody,

I have this one log file that is going from yellow to green back to yellow every 3 minutes.
The xymon-client is installed on a MySQL server.

When the BB Display goes to yellow it indicates:

Warnings in /opt/mysql/log-error/zzzzzz-error.log
yellow Logfile not accessible

But I see activity in the log.

However, the log file does exists there with the proper permissions for everyone to read.
-rw-r--r--  1 mysql mysql 44143540 Oct 29 10:02 zzzzzz-error.log

When it turns green, it indicates:
No entries in /opt/mysql/log-error/zzzzzz-error.log
Full log /opt/mysql/log-error/zzzzzz-error.log

But I see activity in the log.

What could be causing this flopping from green to yellow and back to green?
Thanks in advance.

Every 3 minutes is a bit peculiar because the client message with the log
entries gets sent every 5 minutes. Could it be that there are two client
processes running at the same time?

Permissions on the file look OK, but it could be that permissions on
directory tree are not sufficient.

Hi,

Lately I've been having a problem with one log file, it goes from green to yellow almost every 3 to 5 minutes.

I'll get 'Logfile not accessible'. The logfile is  in '/opt/mysql/log-error/xxxxxx-error.log'

It exists, it has 777 permissions, it is constantly being written too, it is only 52 mgs.

I have restarted xymon-client on the server.

Here is the rest of the error:
Full log /opt/mysql/log-error/xxxxxx-error.log
Cannot open logfile /opt/mysql/log-error/xxxxxx-error.log : No such file or directory

Here is the 'ls' command on it.


-rwxrwxrwx 1 mysql mysql 54394406 Jan  7 16:23 /opt/mysql/log-error/xxxxxx-error.log

Thanks in advance.

My guess is that the xymon user doesn't have permissions in one of the directories in the tree.

Do an  "ls -l /opt /opt/mysql /opt/mysql/log-error"
