perfSONAR User Q&A and Other Discussion

[Phil Reese <>]

    More data on the issue:
    
    I was basing the 'no cron job running' by looking at the output of
    'crontab -l', I've since learned that properly formatted files, put
    in /etc/cron.d/ will run as if part of the crontab system.  In all
    the cases I've looked at there has been a properly formatted
    'cron-service_watcher' file in that directory.
    
    Test cases:
    
    1)  Built a system from scratch with Centos7, updated it to
    Cento7.8.
    Followed the PS documentation pages for loading bundles.
    
    Loaded:
    yum install perfsonar-testpoint
    yum install perfsonar-toolkit-servicewatcher
    
    The results look like all of my endpoint setups.  (see above: No
    cron job (when looking at crontab -l.)  No .conf files in the
    location the servicewatcher script looks for them in.  Initially no
    servicewatcher log files in the /var/log/perfsonar directory. 
    However looking again in an hour or so, the
    servicewatcher_error.log, of zero length did appear.  (this tipped
    me that some type of cron job was, in fact, running)
    
    2)  Next I rebuilt a standard Centos7 from scratch again, as above.
    Followed the PS docs to load bundles.
    
    Loaded:
    yum install perfsonar-toolkit
    
    Only!
    
    The same results were found.  No config files in
    /etc/perfsonar/{servicewatcher.log, servicewatcher_error.log}, there
    was a file in /etc/cron.d, and the empty
    /var/log/perfsonar/servicewatcher_error.log only appears after the
    cron job runs.
    
    I'm pretty sure I'm on solid ground to suggest there is a bug in the
    servicewatcher function in general.

    This is the start of script that is launched by cron:
    /usr/lib/perfsonar/scripts/service_watcher
    
    #!/usr/bin/perl
    ...
    my ( $status, $res );
    
    my $default_config             =
    "/etc/perfsonar/servicewatcher.conf";
    my $default_logger_config      =
    "/etc/perfsonar/servicewatcher-logger.conf";
    ...
    
    $CONFIG_FILE = $default_config unless ($CONFIG_FILE);
    $LOGGER_CONF = $default_logger_config unless ($LOGGER_CONF);
    
    (for brevity, '...' is used to cut out some code lines)

Please note the location of the configuration file should be in:

/etc/perfsonar/toolkit/servicewatcher.conf

 

And the cron file: /etc/cron.d/cron-service_watcher
