Monitoring HAProxy?

Ok, i think i have something for you. Using this haproxy.cfg file:

frontend stats
    bind :8404
    mode            http
    log             global
    maxconn 10

    timeout client  100s
    timeout server  100s
    timeout connect 100s
    timeout queue   100s

    stats enable
    stats hide-version
    stats refresh 30s
    stats show-node
    stats uri  /haproxy?stats

frontend mysite
frontend hissite
frontend theothersite
frontend google.com

I was able to write a DS to pull in 56 different datapoints for each frontend. Your mileage may vary. My /haproxy?stats is running on port 80, not 8404 (running inside a container where the container runtime remaps from 80:8404. Either way, you can add a property to the host called "haproxy.port" to specify a port other than 80 that your stats page is running on. I'll be publishing this to the Exchange shortly where it will need to undergo code review, but here it is in the meantime: https://github.com/sweenig/lmcommunity/tree/master/haproxy_2_4

FYI, instead of scraping the HTML like the old version did, i dove into the json version of the data. I don't know if this just wasn't available in previous versions of HAProxy, or if someone thought it was easier to scrape the HTML. Either way, it necessitates a new DS since the collection method changes from WEBPAGE to BATCHSCRIPT. You should be able to import it into your portal without changing the existing HAProxy DS. Once you get it working, you can delete the existing HAProxy DS.
