Issue/Introduction

DC is running very slowly and graphs in CAPC are missing data. 

 

Environment

CAPM 3.5

Cause

When looking at the DC, the file system is full:

# df -h

/dev/mapper/ehealth-CA 44G   40G  1.3G  97% /opt/CA

# du -a /opt/CA | sort -n -r | head -n 10

41840876 /opt/CA

41840856 /opt/CA/IMDataCollector

40937984 /opt/CA/IMDataCollector/apache-karaf-2.4.3

30607076 /opt/CA/IMDataCollector/apache-karaf-2.4.3/dcdebug

30607072 /opt/CA/IMDataCollector/apache-karaf-2.4.3/dcdebug/On-Demand-Log

8517704 /opt/CA/IMDataCollector/apache-karaf-2.4.3/data

5122932 /opt/CA/IMDataCollector/apache-karaf-2.4.3/data/log

3298060 /opt/CA/IMDataCollector/apache-karaf-2.4.3/data/karaf.out

2964312 /opt/CA/IMDataCollector/apache-karaf-2.4.3/data/log/Exception.log.2

1520392 /opt/CA/IMDataCollector/apache-karaf-2.4.3/data.bak

Resolution

The space may be taken up by DCDEBUG logging located under: 

 /opt/CA/IMDataCollector/apache-karaf-2.4.3/dcdebug/On-Demand-Log

You can run ls -la and remove the largest files in the directory to get your space back.

Additional Information

This issue is resolved in 3.6 and up:

 

Symptom: The dcdebug OnDemand (discovery) log files are not always truncated properly or cleaned up.

Resolution: Completely overhauled dcdebug log cache mechanism.
