Detect database outages and failures faster by monitoring DB2 database with Site24x7 plugins. Use these key indicators to ensure continuous functioning of your DB2 servers.
This document details how to configure the DB2 plugin and the monitoring metrics for providing in-depth visibility into the performance, availability, and usage stats of IBM DB2 servers.
DB2 performance monitoring metrics:
Use our wide array of metrics and get notified of hazardous errors that require your attention. DB2 monitoring helps to keep track of unexpected trends through our metric graphs and troubleshoot as quickly as possible. Various out-of-the-box metrics we support are:
Number of bufferpools
The bufferpool is a part of the main memory space allocated by the database manager. The purpose of the bufferpool is to cache entries and their attributes. The number_of_bufferpools helps to efficiently optmize the memory used by the database and increase its overall performance
Total logical reads
total_logical_reads is the sum of data, index and XDA logical reads
Total physical reads
total_physical_reads is the sum of physical reads of data, index and XDA
Total hit ratio percentage
The total_hit_ratio_percent is a measure of how often a page access is satisfied without requiring an input/output operation
Data logical/physical reads
The data_logical_reads and data_physical_reads gives the sum of data logical and physical reads respectively in the DB2 server
Data hit ratio percentage
data_hit_ratio_percent is the individual hit ratio percentage specific for data bufferpool
Index logical reads and hit ratio percentage
index_logical_reads gives the index bufferpool logical reads and index_hit_ratio_percent is the index bufferpool hit ratio percentage
XDA logical reads and hit ratio percentage
xda_logical_reads gives the XDA index logical reads and xda_hit_ratio_percent is the XDA hit ratio percentage
How it works?
- Log-in to your Site24x7 account. Sign up here if you don't have one.
- Download and install the latest version of Site24x7 Linux agent
- Install the IBM DB2 plugin
- The agent will execute the DB2 plugin extension and push the data to the Site24x7 server
Prerequisites:
- The DB2 plugin uses the "ibm_db" module to interact with the DB2 server.
- Download the 'ibm_db-2.0.7.tar.gz (md5)' file from https://pypi.python.org/pypi/ibm_db/
sudo wget https://pypi.python.org/packages/54/8a/54857a841cbd485d68f9852dfc16d27b069987a65ade38bb9288471ae98b/ibm_db-2.0.7.tar.gz#md5=08d5071d18b201c7a23249c676f1b84f
- Extract the file
sudo tar -xvzf ibm_db-2.0.7.tar.gz
- Go to the directory where the file is extracted
cd ibm_db-2.0.7
- Install the module
sudo python setup.py buildsudo python setup.py install
DB2 plugin installation:
- Create a directory with the name "ibmdb2", under Site24x7 Linux agent plugin directory - /opt/site24x7/monagent/plugins/
sudo mkdir ibmdb2
- Download the "ibmdb2.py" from our GitHub repository and place it under the "ibmdb2" directory
sudo wget https://raw.githubusercontent.com/site24x7/plugins/master/ibmdb2/ibmdb2.py
- The default python path given in the plugin script is #!/usr/bin/python. If you wish to provide an alternate python path, replace the existing one preceded by the shebang character "#!".
- Change the values of DB2_HOST, DB2_PORT, DB2_USERNAME, DB2_PASSWORD, DB2_SAMPLE_DB to match your configuration
- The server agent will report stats on the performance of DB2 server under the Plugins tab in the Site24x7 web client. In case the plugin is not listed in the Site24x7 web client, restart the agent
sudo /etc/init.d/site24x7monagent restart
Monitoring additional metrics:
- To monitor additional metrics, edit the "ibmdb2.py" file and add the new metrics that need monitoring
- Increment the plugin version value in the file "ibmdb2.py" to view the newly added metrics (For e.g., change the default plugin version from PLUGIN_VERSION = "1" to "PLUGIN_VERSION = "2")
