DCE Server system logs

This question was originally posted on DCIM Support by Raza Khan on 2017-04-04


My client had an incident few days ago, their chillers malfunctioned & the InRow ACs stopped cooling.

but the DCE client was stuck & didn't report anything......My client want to view the server's system logs to identify the root cause of this issue, because the server is frequently showing this abnormal behavior from few weeks.

Can anybody please guide me where I can find the Data Center Expert server's logs ?
Do I have to login to its linux interface & access via serial or something ?
Or if I can find it on web client ?

Hi Raza Khan,

My client had an incident few days ago, their chillers malfunctioned & the InRow ACs stopped cooling.

First, have you looked directly at the InRow ACs interface when an incident occurred, was it identified, recognized, etc?

but the DCE client was stuck & didn't report anything......

To be precise, the DCE client does not send any notifications, but only displays (visualy and audio) the current state of the DCE server and monitored devices (via DCE server). Yes, indeed, the DCE client can hang, but it has no effect on the DCE server. It is highly recommended, after all, not to rely solely on the DCE client, but to configure the sending of notifications when incidents occur, similar to yours.

My client want to view the server's system logs to identify the root cause of this issue, because the server is frequently showing this abnormal behavior from few weeks.

DCE server or DCE client? This is very important for further understanding the essence of the problem. Next, I mean the DCE server:

  1. First of all, you need to look at the history of events for a specified period of time on your problem device using the DCE client (the context menu Show Alarm History on your device). If the event or incident you are interested in is on the alarm history, then you need to make sure that the appropriate alarm notification and other response actions are configured.
  2. If the event or incident is not listed in the above alarm history, either there is a communication problem with the device, or with a DDF-file on the DCE server (very unlikely).
  3. The event log of the DCE server (not devices) can be seen from the link: https://you_server.domain/desktop/#eventlog (or http://you_server.domain/desktop/#eventlog).
  4. A detailed and therefore difficult to understand log of the functioning of the DCE server component can be seen from the link: https://you_server.domain/nbc/Logs (or http://you_server.domain/nbc/Logs).
  5. And the most useful option is the ability to download from the DCE server a package of the most important and detailed logs and information files of its functioning as Linux server (and not just the software components of the DCE server). This is done by link: https://you_server.domain/capturelogs (or http://you_server.domain/capturelogs). See also this post .

Do I have to login to its linux interface & access via serial or something ?

Unfortunately not, see also this post 

I am always glad to help.

Thanks a lot for a detailed answer, much appreciated.

Well I've got it, I've downloaded the "Capturelogs" package & now the question is how do I view these logs & let my client study it ?

its like a package of so many files.

Yes, of course, as I wrote in :

It is usual *nix standard of file archive, which easily opens, for example, 7-Zip file archiver under Windows.

 In your situation I think it is useful to study these files from tarball:

  • /data/logs/watchdog.log -- DCE server software related log;
  • /hs_err_files -- normal if this Java crash logfile directory is empty;
  • /var/log/messages -- Linux server related main logfile;
  • df_output -- status of free harddisk space on the server (output of "df" command);
  • pg_alerts -- dump of PostgreSQL tables "alerts" (what we see in the DCE client in the context menu Show Alarm History on your device);
  • pg_eventlog_message -- dump of PostgreSQL tables "eventlog_message" (what we see to the link https://you_server.domain/desktop/#eventlog (or http://you_server.domain/desktop/#eventlog);
  • ps_output -- list of all running processes on the Linux server (output of "ps" command);
  • top_output -- top 10 most resource-intensive processes on a Linux server (output of "top" command).

I am always glad to help.

Hi Raza Khan,

You can check the Event Log tab on the DCE web client, to see if it shows anything useful related to the issues you had with the chiller and cooling units. Otherwise you will need to contact your local Technical Support and provide them with the DCE capturelogs and the logs from the units themselves.
The instructions below show how to retrieve the latest DCE capturelogs, assuming it is v6 or later.

  1. For ISXC version 6.x or higher, type in the following line:  http://<ISXC_IP>/capturelogs
  2. The last capture server file generated will be listed.  You should generate a new capture server log by clicking on ""Create Server Log Archive"".  Let the new file generate.  Once complete, download the file and send it to your local technical support.
