Hi guys. Way back in the ancient mists of time I remember seeing some daemon monitoring app. I can't remember what it was called though. It basically was a tool that ensured that particular daemons on a host were always running. Ie, if they crashed or whatever the monitoring app ran the appropriate rc script to restart them. Anyone know what I'm talking about or a good app that does this?

There is daemontools, healthd (FreeBSD Only sorry) off the top of my head. - Drew
Anyone got a link. When I search for daemontools I get lots of links to the CD/DVD emulation software for Windows. Regards On Mon, 2004-09-13 at 00:04, Drew Broadley wrote:

In addition to this, qmail, djbdns both use daemontools as their daemon maintenance/monitoring.

I spoke too soon. I did the same and found it. No decent RPMs though. And in thinking about it Nagios is probably a better solution overall. Regards On Mon, 2004-09-13 at 15:20, Jodi Anderson wrote:

On RedHat RHEL 2.1. I don't think so. Regards On Mon, 2004-09-13 at 15:48, Drew Broadley wrote:

it _should_ be in your package system.

Can't say i've used RH. On a side note for others: http://summersoft.fay.ar.us/pub/qmail/daemontools/redhat-9/ Looks like there is sufficent rpms for the build.

Uhm, init? Regards, -- Aristotle "If you can't laugh at yourself, you don't take life seriously enough."

netsaint. init won't do much when something like mysqld gets wedged and stops respoding. Partly because mysqld hasn't actually exited, and partly because init doesn't spawn mysqld.. but netsaint will check things like mysqld periodically and take some action when it stops responding. Usually it'll mail an admin, but you can configure it to bounce mysqld. Be warned, this doesn't always work out as well as you might expect.

Netsaint no longer exists due to trademark or copyright problems (or something like that). The project was renamed to nagios and can now be found at http://www.nagios.org/. Nagios works really well for monitoring network and host health, but it is quite time consuming and complex to setup and tune to your particular environment. I probably wouldn't recommend it for monitoring / restarting a single service - the overhead just simply isn't worth it, write a simple shell script! However if you have a more complex environment with service dependencies, or services on several servers that you need to monitor then nagios can come in extremely handy. HTH.

I am familiar with Netsaint/Nagios. A bit more heavy weight than I'm looking for. But certainly an idea worth thinking about. Regards On Sun, 2004-09-12 at 23:34, Matt Brown wrote:

I'm not about to forsake the SysV startup scripts I have with RH to use init to monitor my daemons. Init might be good for gettys and swiching run levels but that is about it these days. Regards On Sun, 2004-09-12 at 20:47, A. Pagaltzis wrote:
