HP Diagnostics includes two server processes: Commander and Mediator. In a Diagnostics installation there will be a single Commander, which can be integrated with HP Business Service Management, HP Performance Center, HP LoadRunner, or operated independently. Depending on the number of applications and systems to be monitored, there could be dozens of Mediator servers in your environment. Mediators are used as a proxy server and load balancer, and all collected data will reside on your Mediator(s).
When installing from the command-line, be prepared to hit “Enter” 31 times to page down through the agreement.
Step 2: Choose an installation directory.
The software can be installed on local storage or NAS. It can be installed on any drive or mount point of your choosing.
Step 3: Choose Server Mode
Both the Commander and Mediator are installed using the same binaries. There is also an option on this page if you are an HP SaaS customer.
Step 4: Time synchronization
Time synchronization is key to data collection in Diagnostics. If Diagnostics detects that a unit of data has a corrupted timestamp, the data will become corrupted. For this reason, I always recommend to customers that they use “Synchronize with system time.” While synchronization with a time server would be desirable, if the Diagnostics server cannot reach the NTP server, corrupted data will result. Even if the local system time is slightly off, it will at least be consistent and accessible.
Step 5: Connection to HP BSM
This option does not establish a connection from Diagnostics to BSM. The only functionality this option exposes is the option to download Diagnostics Agents from a screen in BSM. It is very unlikely you will want to select this option.
Step 6: Alert Settings
Diagnostics enables alerts to be sent via email (SMTP) and SNMP trap. Alerts settings must be configured on all Mediator servers. Previously, this required editing the alert.properties file directly. Now, it is conveniently exposed in the installation.
At this point your Diagnostics server installation is completed and you are ready to install Agents.
