A mod_gearman chart














Some thoughs on mod_gearman benefits.

  • It calls back  Gearmand, so it can be fitted in a vlan behind a firewall and you do not have to open any ports towards the vlan;
  • You can have more than one worker to monitor a host or service. They share the load, so you have a round robin balancing and if one faints, the others take all the checks and execute them. So, you have an easy way to  redundancy for the workers.

In this chart I “collapsed” the gearmand daemon under the  “Monitor” box.
