CA Service Management

Dear team, 

We are receiving alerts that C drive is getting full in Catalog server. When checked the same, logs folder occupies around 25GB. Shall we move the old logs or any other content in CA folder to free up the space.

Please suggest.

Thank you,

Divya Arunachalam

Hello Divya

The old log files can safely be moved to a different folder. These are:

view.log

error.log

\view\ServiceCatalog.log

\view\tomcat_view.log

Which files are taking up the most space in the \logs\ folder? The size and number of many of the log files can be controlled by modifying the %USM_HOME%\view\conf\log4j.xml file. For example, the view.log file section looks like this:

  <appender name="view" class="org.apache.log4j.RollingFileAppender">
    <param name="File" value="${usm.home}/logs/view.log" />
    <param name="MaxFileSize" value="20MB" />
    <param name="MaxBackupIndex" value="100" />
    <param name="Threshold" value="INFO" />
    <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="%d{yyyy/MM/dd HH.mm.ss.SSS} %-5p [%t] [%c{1}] %m%n" />
    </layout>
  </appender>

The "MaxFileSize" and "MaxBackupIndex" settings will control the size of view.log files, and the number of files which are kept in the \logs\ folder. The setting above will allow a maximum of 100 view.log files each of which is 20MB in size.

If the space is being used by different files, please let us know which files are using all this space and we'll investigate further.

Hi Steve,

I have moved the old log files and the setting we have is same as above. Still we have some files in logs folder.

Have attached the screenshot of the same. Please help in what are these files and whether we can move them.

Thank you,

Hi Divya

There's no screenshot attached I'm afraid. Which files are taking up all of the space?

Steve

Hi Steve, Inserted inline. Please check below.

Hi,

There are two types of file there, the .mtmp and the .hprof - both are indications that the java processes behind Catalog are running out of memory, and are dumping information to disk. You may need to look at tuning the resources of both the machine, and how much Catalog is allowed to use.

However, if you just need a quick fix to tidy things up for the moment, then they can be deleted if the CA Service Catalog and CA Service Accounting services are stopped.

Hi Iain,

Please confirm if the below steps are right to perform the same.

1. Stop CA Service Catalog

2. Remove all files with .mtmp and .hprof from logs folder.

3. Start the service

Also application will not be disturbed, right because of the deletion.

Thank you,

Divya Arunachalam

Hi,

as long as Catalog/Accounting is fully stopped, it is safe to delete the old memory dump files, yes.

Iain

Ok Iain, will try that. Thank you.

The other thing to watch out for when space is consumed in the logs folder by the "jms-data" folder. This is the cache for the message queue system, and shouldn't be deleted while any CA Service Management components are running. There will always be some files in here, and if you do delete them they'll have to be rebuilt on the restart, so I'd look at the ones Steve has mentioned for space clearing first.

regards

Iain
