Cisco Systems 10200 manual Examining Heap Usage, Checking the DNS Server

Chapter 3 Monitoring and Backing Up the BTS

Archiving Your Database

Step 6 Restore the Solaris “date” command to create the system Flash Archive. Enter:

mv /bin/date /bin/date.orig mv /bin/.date /bin/date

Step 7 Create the archive. Enter <hostname>#flarcreate -n <archive name> -x /opt -S -c /mnt/<file

name>

Note Example archive name: flarcreate -n CCPU-EMS-x /opt -S -c /mnt/secems04.archive

Step 8 Back up the /opt directory. Enter tar -cvf - /opt/* gzip -c >/opt/<hostname_release>.tar.gz Step 9 Restore the original configuration. Enter:

mv /bin/date /bin/.date

mv /bin/date.orig /bin/date

Step 10 Unmount the NFS server. Enter umount /mnt

Examining Heap Usage

Heap is memory BTS reserves for data it creates as its applications execute. BTS audits heap usage of all the processes started by a platform, CA, AIN, POTS, EMS and BDMS. Heap auditing is added to the ADP process.

When heap usage of a process goes beyond certain threshold level, BTS generates an alarm. The alarm clears when heap usage goes below the threshold level.

Heap audit does the following:

•Monitors traces of heap usage in the last four periods for each process

•Measures heap usage of each process started by the platform once a day at 4 a.m

•Issues a minor alarm if the heap usage of a process exceeds 70% of its max heap size limit

•Clears a minor alarm if the heap usage of a process drops below 68% of its max heap size limit

•Issues a major alarm if the heap usage of a process exceeds 80% its max heap size limit

•Clears a major alarm if the heap usage of a process drops below 78% its max heap size limit

•Issues a critical alarm if the heap usage of a process exceeds 90% its max heap size limit

•Clears a critical alarm if the heap usage of a process drops below 88% its max heap size limit

•Reports, via trace logs, the last twenty heap measurements, including the time and the value for each process

•Clears heap usage alarms when process restarts

Checking the DNS Server

To check the DNS server, do this for all nodes.
