Some time ago I wrote about selfdiagnose-the-world-according-to-my-atg-application.
Since then SelfDiagnose has added some nifty features. The latest release of SelfDiagnose now adds support for OGNL. This gives SelfDiagnose some extra punch. I can now use constructions like:

<checkvaluematches
    value="${@java.lang.Integer@parseInt(configList.length)}"       
    comment="Number of configured Endeca instances"
    pattern=".*" />

or constructions like

 <checkendecaservice host="${configList[0].host}" 
   port="${configList[0].port}" 
query="N=0" 
  comment="Endeca instance 1 connection test"/>

The ${configList[0].port} is a typical OGNL construction.

The CheckEndecaService can also return the Endeca com.endeca.navigation.ENEQueryResults response.
With OGNL you can easily dissect this Endeca response.

This can be extremely handy to query for the latest Forge or pipeline version of an Endeca build in the different ATG environments were you cannot directly access those services! For instance in production.
