Help with logs

Atul Bhagwat Nov 13, 2017 6:35 AM

Hi Folks,

We have a 3 node Tableau server ( Primary + 2 Workers)

Today morning, we got notifications from the server from one of the worker nodes

nxxxx.us.domain.com

Monday,
November 13, 2017 8:03:16 AM EST

DOWN:
Gateway service, nxxxxxx.us.domain.com:80

Monday,
November 13, 2017 8:03:31 AM EST

UP:
Gateway service, nxxxxxxx.us.domain.com:80

Verified that this was not a scheduled restart.

No tabadmin script ran during that time.

Checked that particular worker node.

Task manager did not show any server restart. ( checked UP time of the server)

However, the clustercontroller logs do not give any info, as to what could have triggered the tableau node to restart.

Where should I dig in more to find answers?

Regards,

Atul B

A couple places to look.

1. Event viewer within this worker node. See if the gateway was a "dead component" and then was restarted.

2. The log for the gateway process on the worker

Thanks Jeff,

Did see this earlier in event viewer, however as this was a warning for backgrounder, ignored it.

Restarting dead component 'Tableau Server Backgrounder 0'.
This was like 30 min before the node restarted.
Couple of our Win AD ACL groups that failed to sync..

Did not see anything for Cluster controller or gateway in event viewer.
also, under httpd access logs for that time, all I can see are 200 ok requests..
No Activity logs generated as mentioned below:
Tableau Server Gateway Process

somehow, I am unable to see the error.log file, may be its locked by the system for now.
Although don't see a current date on it.. So not sure.
cluster controller logs are on info level. No surprizes in there as well.

Well, I'm not sure where else to direct you besides to open up a case with Tableau Support. Generally, as long as you have enough system resources (i.e. cpu, ram, disk), then the gateway process is light weight and doesn't crash.

Do you have any server customizations in place?

What version of server?

I guess will wait for the error.log to be accessible.
No Server customization.
Version 10.2.2

are you looking in the proper sub-directory for the error.log? Here is where it's located on our on-premise deployment.

Yes Jeff.
I am looking in this location.
The error.log file is locked at the moment it seems.

What app are you trying to open it with?

When I try with wordpad, then I get the error:

But when I try with notepad, then it opens...

Do you get access denied or "the file is in use by another app"? The access denied message is usually a permissions thing...

Yes Jeff. I thought so too.
however, I can click the access log files in the same location and it works.
So don't know if its the permissions that are in way.
Also, the error only shows up for the current files.
If I open an old access file ( earlier date at the same location) it works.

You can try and do a tabadmin ziplogs and see if you can get to the error log within the zipped up copy.
