Questions on Infrastructure Agent

Products

• CA Application Performance Management (APM / Wily / Introscope)

Issue/Introduction

Here are some questions about the infrastructure agent:

Q1.  does this agent also work under version 10.7 SP1?

Q2,  Can the IA be installed on a customer's computer to monitor their web server?

Q3. in which configuration on the IA must the destination address of the MOM be entered?

Q4.  Do we need the Host Monitoring Agent for Apache monitoring or ONLY the Web Server Monitoring Extension OR both?

Resolution

A1. APM 10.7 SP 1 is no longer supported since 12/23. So it may or may not work. But that combination is not tested and unsupported. Upgrading the EM to APM 10.8/22. or migrating to SAAS is recommended. Support can assist on that.

A2. See Web Server Monitoring
Yes you can. In the documentation. Install the Web Server Monitoring on any host behind a firewall. Configure the monitored web servers to publish the performance statistics to a URL on that web server. The Web Server Monitoring periodically connects remotely using HTTP or HTTPS to the web server, collects the statistics, and reports the statistics to Introscope. Configure the Web Server Monitoring to discover and monitor any new web server that appears on the specified subnet or subnets.

A3. Connecting APMIA to EM
You can modify the default settings when you install the agent, or after installing the agent by modifying the Infrastructure Agent IntroscopeAgent.properties file.

A4, 

Depends what you are doing

Host Monitoring
DX Application Performance Management Host Monitoring (Host Monitoring) is an extension that provides powerful systems management through the industry-standard SNMP. Host Monitoring provides health metrics such as server % CPU utilization and memory, and network disk and storage statistics. Correlate the host infrastructure performance metrics with other DX Application Performance Management monitored application performance metrics. This correlation helps you quickly determine whether poor host performance is the source of application performance issues.
Host Monitoring uses an SNMP-based Collector Agent to receive host performance metrics from the Host Monitoring Probe Agent. The Collector Agent reports the metrics to the Enterprise Manager.

 

Web Server Monitoring

Use Web Server Monitoring

Web server administrators can use the monitor to diagnose the following issues:

• Web server availability

  When users report that certain web applications are unavailable, the monitor reports availability of all web servers. Administrators are able to determine web servers availability.
• Slow response times

  When users report slow page download times, the monitor shows the servers that are experiencing the highest load and the highest response time.
• Domain Name System (DNS) issues

  The monitor shows the web servers that are performing excessive DNS lookups.
• Load balancing issues

  The monitor shows the relative amount of load for each web server and highlights over-loaded and under-loaded web servers.
• Web server configuration issues

  When administrators want to verify web server configuration issues, the monitor highlights worker processes or thread issues, cache misses, and so on
