Re: Monit start delay only on boot

Correct, I want to drop the start delay down to 30 seconds from my current setting of 120 so service restarts will have less lag.  However, there could be some things like JAVA-based applications that need more time to startup completely after a server reboot.

This would be best solved if a new option was added to monit that could check the uptime (/proc/uptime) and allow for a special delay at startup separate from the current "with start delay."

Maybe something like this:

set daemon 30
    with start delay 30
    and bootup start delay of 120

Then another setting like:

set bootup start delay period 600

so the first 10 minutes of the server booting up would have an extra 120 seconds of delay.


I looked at doing something custom with systemd and it's going to be difficult/impossible to do a long delay reliably.

Hi Dave,

if monit depends on some services on your system, it'll be maybe better to set the dependencies and drop the start delay option from the configuration file.

Best regards,

Loving monit.  Just started using it a few months ago to deploy certs from a central server to about 800 servers/VMs.  Monit will restart/reload each service (Apache, Postfix, Haproxy, Nginx, etc.) that references an LE cert when it's renewed every 60 days.  This is working great.

I am remotely monitoring Monit using Icinga/Nagios and they are working very well together.  I am moving many of my Icinga checks into Monit using scripts to generate /etc/monit.d/*.cfg files custom for each server.  Then a single Icinga/Nagios check using will be customized to each box.

The only minor issue is the delay start that is needed for bootup but causes "connection refused" in the monit web interface used by when monit restarts.

Would it be possible to have an option added to only delay XX seconds on a fresh boot where the uptime is less than a few minutes?  Or allow the monit web interface to immediately accept connections if a recent statefile exists?
