ACORN

Description

Check whether acorn process is running and if it is not, start acorn for Snapshot, SOH, and/or PCAD. Acorn itself extracts needed data from the data sent through data ports. The extracted data are saved in tracelog (*.tl). Which data are extracted depends on the *-msids.list which lists categories and their chandra msids.

The data are updated only when Chandra is in comm pass (see Replan Central "Chandra Events" seciton to find when is the next comm pass.)

You can check whether the acorn processes are running by issuing the command:

• ps aux | grep acorn

This will generate something like:
