mon command not found #30

Closed AnthonyLELUYER closed 2 years ago

AnthonyLELUYER commented 5 years ago

Hi,

I'm trying to update my naemon configuration to Ninja, and try to make a cluster with Merlin. However, although the installation of Merlin went OK (no error), I don't have the "mon" command. I can't find it.

Can I ask which environment you are working on ? I'm trying on CentOS 7, as I can find all the requirements, unlike with Debian 9.

Hi,

We use CentOS.

The mon command is located in the apps directory, and I guess there are no install scripts, other than the spec file, that ensures they are installed. When built there is a apps/op5 executable, which is the same as the mon command. Checkout the code in the spec file: https://github.com/op5/merlin/blob/efedb2be49225d9802de2d1739534da1f49301c0/merlin.spec#L137

Hi @jacobbaungard

Thanks a lot. There is no symbolic link on the op5 file located in apps, so that's why I didn't have the mon command. It also seems like every steps on this file were either failed or ignored, although the make and make install went OK.

I'm not used to spec file, just read that it was used to create RPM package. Do you know how %buildroot is defined ? As well as %_bindir ?

That file seems odd, it will %configure with --with-naemon-config-dir=/opt/monitor/etc/mconf although my naemon config dir is located in /etc/naemon/

Did I miss a step ?

/opt/monitor/etc/mconf is the default merlin module configuration path for OP5 monitor, which is why it is configured like that. I assume the default is /etc/naemon which is perfectly fine.

Buildroot is defined here which is just the current folder were the source is being built: https://github.com/op5/merlin/blob/efedb2be49225d9802de2d1739534da1f49301c0/merlin.spec#L33

Actually I took a look and I think the makefile actually does install the scripts located in apps. Do you have the op5 script in your install path? If you do I think it would be enough to locate that (which op5) and then make create a symlink from op5->mon in that same folder.

Did you manage to get this to work?

Hi,

I will close this old issue, assuming it is no longer relevant. These days we build RPM packages for easier installation including the mon command. Instructions can be found here: https://itrs-group.github.io/monitor-merlin/

Feel free to open a new issue if you are still having issues.
