Config file

To create a custom configuration file copy cronwrapper.cfg.dist to cronwrapper.cfg.

The file needs read permissions for all users (0644).

# -----------------------------------------------------------------------------
# CRONWRAPPER * config
# -----------------------------------------------------------------------------

# ----- shared values:
LOGDIR=/var/tmp/cronlogs


# ----- for cronwrapper
# deny multiple execution of the same job? set 0 or 1
SINGLEJOB=1


# ----- for sync of local logs
TOUCHFILE=lastsync
TARGET=get-cronlogs@cronlogviewer.example.com:/var/tmp/allcronlogs/$( hostname -f )
SSHKEY=/root/.ssh/id_rsa_get-cronlogs@cronlogviewer.example.com

# force rsync even if no change was found - time in sec
SYNCAFTER=3600

# disallow hosts that have no domain in hostname -f; set 0 or 1
REQUIREFQDN=0

# -----------------------------------------------------------------------------

For the execution of all cronjobs on the server there is just one variable to define a place where to store output files.

Variable type description
LOGDIR string Ouput dir of all logfiles when using cronwrapper.
It is used by status script and sync script to read data from here. Default: “/var/tmp/cronlogs”
SINGLEJOB int 0 or 1; 1=deny multiple execution of the same job (default)

For an optional rsync script to collect all logs of all servers on a central server (see Cronlog-Sync):

Variable type description
TOUCHFILE string sync: filename of touch file to mark a timestamp of the last sync (created in in $LOGDIR); eg. “lastsync”
TARGET string ssh target where to sync files from $LOGFILE with sshuser@targethost:/path
Default: get-cronlogs@cronlogviewer.example.com:/var/tmp/allcronlogs/\$( hostname -f )
SSHKEY string filename to ssh private key to connect passwordless to $TARGET
SYNCAFTER int time in sec; default: 3600 (1h); time before syncing the logdir even if it has noch change
REQUIREFQDN int 0 or 1; block sync if hostname -f has no FQDN

Environment file

In a environment file you can set a pre defined shell environment for all your cronwrapper cronjobs. This is completely optional. Just keep in mind that the possibility exist if it is needed once.

To create a custom environment file copy cronwrapper.env.dist to cronwrapper.env. The file needs read permissions for all users (0644).
