Healthchecks / Alternative for five.z2monitor?

KrissiK · February 2, 2024, 9:18am

We are using haproxy for loadbalancing and I'm wondering what is a good way to let haproxy know about the health status of the plone workers.

At

five.z2monitor is recommended but it is deprecated. Is there an newer alternative for it?

Or how to do healthchecks right for Plone6?

Most simple check form outside I use: There is a ok view coming with caching disallowed.
I.e. https://plone.org/ok

Thank you - did I miss some documentation about this?

Do you know if /ok is handled in the same threads as normal requests?

It's a simple view, no special handling, see

github.com

plone/Products.CMFPlone/blob/master/Products/CMFPlone/browser/okay.py

from Products.Five.browser import BrowserView


class OK(BrowserView):
    """Returns OK.

    Useful for automated checks, for example httpok, to see if the site
    is still available.  For this you don't want to query a possibly
    expensive page.  And you don't want to query anything that may be
    stored in an intermediate caching server.

    Calling /ZopeTime can work too.  But if you use
    experimental.publishtraverse, this will either give you a NotFound,
    or log a warning each time it is called, due to lacking
    permissions.  And this may happen in core Plone in the future too.
