Agenda
• Monitoring Alfresco• What is Nagios and Icinga?• How it works?• Alfresco Plugin • Installation and configuration• Screenshots• Resources
Monitoring Alfresco
• Several ways:• JMX• Logging• TCP/UDP• ICMP• Profiling
• Why monitoring?• Control• Metrics• Provisioning• Bottlenecks• Problems• Performance• Scalation• Alerts• Threshold• Historic
How Can I Get Full Monitoring of Alfresco?
How Can I Get Full Monitoring of Alfresco?
• Nagios or Icinga + nagios4alfresco plugin
What is Nagios and Icinga?
Nagios• Open Source
monitoring software
• 1999 – NetSaint

• Various notification options, alerts and scalations
• Plugins and modules
Icinga
• Nagios fork 2009
• Supports DB backend
• Icinga-web PHP
• Icinga Reports based on Jasper Reports (optional)
How it works?
Check plugins• “check_smth”
• Standard (TCP and UDP) plugins
• Service specific (MySQL, IMAP, SMTP, etc.)
• Custom plugins (check_jmx)
• Derivates check_jmx check_alfresco
How to monitoring Alfresco?
• TCP and JMX• Nagios plugin for Alfresco 1.1
• http://addons.alfresco.com/addons/alfresco-nagios-icinga-plugin/• For Alfresco Enterprise 3.2 and above• Easy and quick install
• README file• Copy check_alfresco and check_alfresco.jar files to plugins/libexec
directory • Copy and edit alfresco-server.cfg• Copy and edit alfresco-commands.cfg • Reload Nagios config
• Install pnp4nagios• Performance data supported on plugin• Enable performance data on Nagios

• 11 OS and network related checks

New plugin version 1.2
• New version of nagios4alfresco plugin• Tested with Alfresco Enterprise 4.1.1
• Added SOLR + Workflow info• Commented Lucene, Hibernate, Audit storage checks• Changed default CIFS ports to 1445 and 1139
• Released Nov 13th
• Next releases and roadmap• Add more SOLR information• Add more OS related and protocol specific checks
Monitoring Community with JMXNot Alfresco EE - JMX layer specific, but Tomcat, for example:
• check_alfresco connections to Tomcat variables (File Descriptors, Load Average, Heap Memory Used, Number of Threads or Share Caches)• check_http 80 and 8080 ports for apache web proxy and tomcat• check_snmp for several general parameter (disks, memory, cpu, load, swap)• check_tcp conections to CIFS, FTP, RMI ports of Alfresco ECM• check_tomcat for servlet container monitorization via server status• check_mysqld for nice mysql graph stats and db net traffic
Access
• http://<yourserver>/nagios - classic web interface for Nagios• http://<yourserver>/icinga - classic web interface for Icinga• http://<yourserver>/icinga-web - new web interface• http://<yourserver>/pnp4nagios - graphs (and mobile access)
Icinga classic web interface (Nagios)• Always monitoring! • Nagios4Alfresco Plugin
+33 checks
How Icinga Looks Like?
pnp4nagios: Graphs Everywhere
• Rrd tool + nagios pefdata
Mobile Monitoring
• pnp4nagios has its own mobile interface
Troubleshooting• Ports and firewall (open only to your monitoring server!):
### RMI service ports ###alfresco.rmi.services.port=50500avm.rmi.service.port=50501avmsync.rmi.service.port=50502attribute.rmi.service.port=50503authentication.rmi.service.port=50504repo.rmi.service.port=50505action.rmi.service.port=50506deployment.rmi.service.port=50507
• Credentials•Change alfresco-jmxrmi.access and alfresco-jmxrmi.password (out of class path)•Read only for checks!!•Test with jconsole

• Drop me an email: [email protected] • IP address• JMX port• JMX read only user and password
• I will give you web access to see your server stats• Remember, personal project! Not SLA to apply :P• Up to 20 servers total
