System Crons

Crons

Periodic tasks will run from the server master instance automatically, you can find the config in the config/{environment}.json file, keyed by 'cron'.

• stats - network chord stats, every hour
• triggers - trigger channels, every 15 minutes
• expirer - bip expirer, every hour

To disable a cron, either remove it from config or set an empty string.

To have these crons handled by your system scheduler rather than the bipio server, disable the crons in config as described. Wrapper scripts can be found in ./tools for each of stats (tools/generate-hub-stats.js), triggers (tools/bip-trigger.js) and expirer (tools/bip-expire.js).

Here's some example wrappers.

Trigger Runner

Cron: */15 * * * * {username} /path/to/bipio/tools/trigger-runner.sh

cd $HOME (date && node ./tools/bip-trigger.js ) 2>&1 >> /path/to/bipio/logs/trigger.log

Expire Runner

Cron: 0 * * * * {username} /path/to/bipio/tools/expire-runner.sh

expire-runner.sh :
