It supposed to be nagios, mine ended up being naemon.
It does now!
The ModGearmanInstall.sh script (
https://assets.nagios.com/downloads/nag ... Install.sh) has been updated to reflect the proper user, and gives you a user flag to override the default if necessary.
Other than that, the instructions located at
https://assets.nagios.com/downloads/nag ... ios_XI.pdf are mostly relevant. I also changed the installation type flag to --type=worker or --type=server
We'll be updating the documentation shortly to reflect those changes.
Let us know how it goes. Thanks.
Thanks for the update. What about server + worker installation on the same server? Is there a flag for that?

The server install/upgrade automatically installs/upgrades a worker locally.
I'm in the process of updating the documentation and putting together some more documentation to more clearly explain workers and queues.

Thanks Troy. It will greatly help if clear upgrade instructions that maintains the existing configuration is documented.
This includes upgrade from version 1 or 2 of mod_gearman.

Yes it will upgrade any version and will maintain the existing configuration (when the
--upgrade flag is used). I'll make sure the documentation is clear that the existing configuration is maintained.
We'll let you know when it's done.

Here is the updated document which references the updated script:

Here is a new guide I wrote on Queues and Workers:

Looks good Troy thanks.
One question. Is it normal for all the worker_host queues to show 0 all the time.
How to confirm it is actually being executed in the target worker servers?

Waiting and running. Always 0.

I assume that because they are all being processed almost instantly, they never seem to appear and stay at 0.
Honestly I've only ever been able to get these numbers to change by stopping all the workers temporarily, at this point there is nothing to run the jobs so the numbers should start to climb from that point.
