  1. Apache Web Server (AWS) Monitoring JBossNetwork Enterprise Manager The Professional Open Source™ Company

  2. Agenda • Supported versions of AWS • Configuring AWS for management • Supported Metrics and Control Actions • Metric Data Collection, Control, and Alerting 2 The Professional Open Source™ Company

  3. Supported Versions of AWS Supported on UNIX (Linux, Solaris, HP/UX) and Windows: • Apache Web Server • 1.3.x • 2.0.x • Covalent Enterprise Ready Server (ERS) • 2.3 • 2.4 3 The Professional Open Source™ Company

  4. Setting up AWS in JBN EM • Steps are as follows • Install AWS on a JBN EM-managed platform • Prepare AWS for management via JBN EM • Start the JBN EM agent on the host running AWS • Launch the JBN EM Console and run a new auto-discovery scan on the platform • Import the AWS instance • Complete resource configuration for the AWS server and virtual hosts • Exercise the AWS instance 4 The Professional Open Source™ Company

  5. Preparing AWS for management • AWS instances support monitoring capabilities via third party DSO’s/modules: • SNMP module (mandatory) • RT module (needed for response time collection) • Installing a module in AWS: • Getting a copy of the binary • Copying the module under the AWS installation • Updating AWS configuration to use the module 5 The Professional Open Source™ Company

  6. Installing SNMP/RT modules into AWS on UNIX SNMP/RT modules can be built from the JBN EM full/agent distributions on UNIX. Prerequisite: AWS must have been configured with --enable-sofor the SNMP and RT modules to be installed. A. SNMP Module: 1. Compile and deposit the SNMP module. cd JBNEM_AGENT_INSTALL_DIR % tar –zxf jbn-em-agent-jboss-1.0.xx/product_connectors/snmp-jboss-1.0.xx.tgz % cd snmp-jboss-1.0.xx % ./build_apache_snmp.sh 2.0 APACHE_INSTALL_DIR/bin/apxs % cp snmp_module_2.0/module/*.so APACHE_INSTALL_DIR/modules % cp snmp_module_2.0/conf/snmpd.conf APACHE_INSTALL_DIR/conf % mkdir APACHE_INSTALL_DIR/var 2. Edit APACHE_INSTALL_DIR/conf/httpd.conf, adding: LoadModule snmpcommon_module modules/libsnmpcommon.so LoadModule snmpagt_module modules/libsnmpmonagt.so SNMPConf conf SNMPVar var ServerName www.mydomain.com:80 (use appropriate domain name and port number) 3. Restart AWS % APACHE_INSTALL_DIR/bin/apachectl restart 6 The Professional Open Source™ Company

  7. Installing SNMP/RT modules in AWS on UNIX (continued) B. RT Module 1. Compile and deposit the module: cd JBNEM_AGENT_INSTALL_DIR % tar –zxf jbn-em-agent-jboss-1.0.xx/product_connectors/rt-jboss-1.0.xx.tgz % cd rt-jboss-1.0.xx % ./build_apache_module.sh 2.0 APACHE_INSTALL_DIR/bin/apxs % cp apache2.0/unix/.libs/mod_rt.so APACHE_INSTALL_DIR/modules 2. Edit APACHE_INSTALL_DIR/conf/httpd.conf, adding: LoadModule rt_module modules/mod_rt.so LogFormat "%S" rt_log CustomLog logs/rt_log rt_log 3. Restart the AWS % APACHE_INSTALL_DIR/bin/apachectl restart 7 The Professional Open Source™ Company

  8. Installing SNMP/RT modules into AWS on Windows Pre-built SNMP/RT modules are included in the JBN EM full/agent distributions on Windows. • Unzip the file JBNEM_INSTALL_DIR\product_connectors\apache-2.0-x86-winnt.zip to APACHE_INSTALL_DIR • Edit APACHE_INSTALL_DIR\conf\httpsd.conf to add: LoadModule snmpcommon_module modules/libsnmpcommon.so LoadModule snmpagt_module modules/libsnmpmonagt.so SNMPConf conf SNMPVar var LoadModule rt_module modules/mod_rt.so LogFormat "%S" rt_log CustomLog logs/rt_log rt_log ServerName www.mydomain.com:80 (use appropriate domain name and port number) 3. Restart AWS 8 The Professional Open Source™ Company

  9. Importing AWS into JBN EM inventory • Make sure AWS and JBN EM agent are running on the managed platform • Launch JBN EM console • Run auto-discovery • Import AWS into the inventory 9 The Professional Open Source™ Company

  10. Auto-discovered AWS instance 10 The Professional Open Source™ Company

  11. Completing configuration of AWS resources Was AWS pre-configured for management? • Yes • Sanity check on console • Configure virtual host resources • No • Perform configuration from scratch • Import discovered virtual hosts • Configure virtual host resources 11 The Professional Open Source™ Company

  12. Verify AWS server configuration Configure AWS server resource • Go to the Inventory/Configuration page for the AWS server • Configuration settings are displayed on the page • Click on the EDIT button under the section titled “Configuration Properties” • Enable auto-discovery of virtual hosts 12 The Professional Open Source™ Company

  13. Configuration settings of the AWS server 13 The Professional Open Source™ Company

  14. Modifying AWS server configuration 14 The Professional Open Source™ Company

  15. Instructions for installing SNMP modules 15 The Professional Open Source™ Company

  16. Configuring AWS virtual hosts Go to the Inventory/Configuration page for the AWS virtual host • Verify/modify configuration settings • Optionally enable service response time collection 16 The Professional Open Source™ Company

  17. Configuration settings of a virtual host 17 The Professional Open Source™ Company

  18. Modifying virtual host configuration 18 The Professional Open Source™ Company

  19. Instructions for installing the Response Time module 19 The Professional Open Source™ Company

  20. Components of AWS Monitoring • Metric data collection • Control • Alerting 20 The Professional Open Source™ Company

  21. Metric Data Collection • Each version of AWS has a “universe” of metrics • Server metrics: • Availability • availability • start time • Throughput • Number of GET requests per minute, Total number of requests per minute, Total number of bytes sent etc. • Resource Utilization • Number of concurrent connections • Virtual host metrics: • Availability • availability • Throughput • Number of GET requests per minute, Total number of requests per minute, Total number of bytes sent etc. • Response Time • service time 21 The Professional Open Source™ Company

  22. List of Apache server metrics 22 The Professional Open Source™ Company

  23. Enabling metric data collection • Configuration supports: • Selection of metrics for collection specifying the collection interval • Modifying collection interval for metric • Disabling collection for metric 23 The Professional Open Source™ Company

  24. Selecting metrics and collection intervals 24 The Professional Open Source™ Company

  25. Viewing metric data 25 The Professional Open Source™ Company

  26. Metric data in chart form 26 The Professional Open Source™ Company

  27. Response time stats for virtual host 27 The Professional Open Source™ Company

  28. Control Actions on AWS resources • Server • Start • Stop • Restart • Virtual Host • None 28 The Professional Open Source™ Company

  29. Scheduling a control action 29 The Professional Open Source™ Company

  30. Alerts on AWS resources • Full range of alerting semantics apply to AWS resources • Alerts • Can be defined on any metric on • AWS server • AWS virtual hosts • Can be combined with control actions on AWS server 30 The Professional Open Source™ Company

  31. Defining an Apache server alert 31 The Professional Open Source™ Company

  32. Defining a recovery alert 32 The Professional Open Source™ Company

  33. Trigger notification on Dashboard for problem alert 33 The Professional Open Source™ Company

  34. Trigger notification on Dashboard for recovery alert 34 The Professional Open Source™ Company

  35. Review • We’ve covered • The inventory and configuration of AWS and embedded services • Metric data collection and display • Performing control actions • Creating alerts on metric values 35 The Professional Open Source™ Company
