The document discusses various free tools that can be used to monitor IBM WebSphere and its components, including Nagios, WebSphere Performance Tuning Toolkit (PTT), Nmon Visualizer, and Apache mod_status. Nagios is an open source monitoring tool that can monitor WebSphere components like servers, JVM, databases, and more using plugins. WebSphere PTT provides real-time performance monitoring of WebSphere. Nmon Visualizer is useful for visualizing performance data from Linux systems. Mod_status allows monitoring of Apache HTTP servers. Examples and resources are provided for setting up monitoring with these various tools.

5. Overview
• Nagios
• WebSphere PTT
• Nmon Visualizer

7. • IS FREE !!! – well open source
• Linux based – runs on RHEL or CENTOS
• Super easy to set up – very well DOCUMENTED 
• Features:
Monitoring - System metrics, network protocols, applications, services, servers, and
network infrastructure
Alerting - Nagios sends alerts when critical infrastructure components fail and recover.
Alerts can be delivered via email, SMS, or custom script.
Reporting - Provide a historical record of outages, events, notifications, and alert
response for later review. Availability reports help ensure your SLAs are being met.

10. Nagios & Websphere
• Basic WAS monitoring
• Up or Down check on soap port of each server
• Up or Down of host machine – via a ping or host up
command
• Plugins:
https://github.com/yannlambret/websphere-nagios - JVM heap monitoring, Server thread pools monitoring - including hung
thread detection, JTA transactions monitoring,JDBC datasources monitoring, JMS connection factories monitoring, JMS 1.0
listeners status monitoring, SIB queues depth monitoring, HTTP sessions monitoring, Clustering support, Administrative
security support
https://github.com/dvarounis/perfservmon - Perfservmon is a Nagios Plugin for IBM Websphere Application Server(WAS)
using the perfservlet web application that comes with each WAS installation. Can monitor - Heap Usage, Web Container
Thread Pool Usage, ORB Thread Pool Usage, JDBC Connection Pool Usage, Live HTTP Sessions, JMS SIB
Destination(Queue, Topic) Metrics

11. Nagios & HTTP
• Basic HTTP monitoring
• Ports up / down on 80, 443 and 8008
• Can monitor for specific codes 500 / 404 etc.
• WAS plugins in the previous slides also monitor HTTP
sessions.

12. Nagios & DB
• Basic up and down check
• Lots of plugins for monitoring
– https://github.com/angoca/monitor-db2-with-nagios - bunch of really useful stuff
- check_hadr_status - works with V10.5
- check_tablespace_size – 9.7 and up
- check_db2diag –9.7 and up
- check_instance_up – 9.7 and up
- check_instance_memory – 9.7 and up
- check_last_backup – 9.7 and up
- check_log_consumption – 9.7 and up
- check_log_usage – 9.7 and up

13. Performance indicators WebSphere
• WebSphere Application Server Performance Tuning
Toolkit (PTT)
• Free, Eclipse based tool provided by IBM
• Yes, it’s free and from IBM and it works 

14. WebSphere Application Server Performance
Tuning Toolkit (WAS PTT)
• Benefits:

27. How to find performance indicators
HTTP Server: mod_status
• Apache module
• HTML Interface:
Ex. : http://www.apache.org/server-status

28. How to find performance indicators
HTTP Server: mod_status

29. How to find performance indicators
HTTP Server: mod_status
• Easy to setup in httpd.conf

30. Nmon Visualizer
• Easier than the excel file
• Open source tool
• Developed by IBM to monitor Smartcloud
• Apache 2.0 License
• nmon files from Linux and AIX, IOStat files, IBM Verbose
GC logs, Windows Perfmon & ESXTop csv data and
JSON data

31. Nmon Visualizer

32. Nagios & DB2 Monitoring
• Each script is individually configurable
• Edit the script directly or use GUI config (nagiosQL)
• Alerting settings are configured at
Nagios level

33. Nagios & DB2 Monitoring
• https://github.com/angoca/monitor-db2-with-nagios
• check_connection_qty - quantity of connections on the
database and the state they are currently in, lockwait,
connecting, rollback etc ..
• check_database_connection – checks a connection to the DB
• check_database_size – set threshold alerts, etc.
• check_lock_wait – 10.5 and above – checks lock waits
• check_memory_usage - usage memory: total, free, usage
• check_open_files – open files per instance
