To debug an InfoHub from the shell, execute a command like:
$gtm_dist/mumps -run InfoHub --action=jobexam [--pidlist=<comma,delimited,list,of,PIDs>]
This command places the output of ZSHOW "*" in a file called infohub-<service>-<infohub id>[-<publisher | noinfo id>[-<xline id>]-<configuration sequence number>.ZSHOW_DMP_"_$JOB_"_"_<cntr>.
If --pidlist is specified, jobexam generates ZSHOW "*" output for only those InfoHub processes that are mentioned in the pidlist.
To debug an InfoHub from within GT.M, invoke the following entry point in the InfoHub API as an extrinsic function:
$$jobexam^InfoHub(InfoHubID,"comma,delimited,list,of,PIDs")
Example:
GTM>if $$status^InfoHub(7421,1) InfoHub ID |InfoHub Name |State 7421 |DEMO |Running Process listing 28981 InfoHub /usr/lib/fis-gtm/V6.0-003_x86_64/mumps -direct InfoHub ^InfoHubMain 7421 28987 NoInfo /usr/lib/fis-gtm/V6.0-003_x86_64/mumps -direct InfoHub ^InfoHubNoInfo 7421 1998603323 1 /home/jdoe/infohub/InfoHub/InfoHub.gld 28985 Publishers /usr/lib/fis-gtm/V6.0-003_x86_64/mumps -direct InfoHub ^InfoHubPublisher 7421 321 1 /home/jdoe/infohub/InfoHub/InfoHub.gld 29085 FileLine /usr/lib/fis-gtm/V6.0-003_x86_64/mumps -direct InfoHub ^InfoHubFileLine 7421 321 1 123 /home/jdoe/infohub/InfoHub/InfoHub.gld GTM>if $$jobexam^InfoHub(7421,"28981,28987") PID [28981] has been notified PID [28987] has been notified GTM>
$ $gtm_dist/mumps -r ^InfoHub --action=jobexam --pidlist=28981,28987 PID [28981] has been notified PID [28987] has been notified $
Both examples place the output of ZSHOW "*" in a file called infohub-<service>-<infohub id>[-<publisher | noinfo id>[-<xline id>]-<configuration sequence number>.ZSHOW_DMP_"_$JOB_"_"_<cntr> for PIDs 28981 and 28987.

The ZSHOW "*" output in the JOBEXAMINE files may contain confidential information gleaned from the monitored components that the process holds in local variables, and, possibly, in Intrinsic Special Variables (ISVs). If that is the case in your InfoHub deployment, ensure that the files produced by this command are appropriately secured. |
