Broken Link Checker
Server load (4 posts)

    Hi,

    I'd like to know what kind of load the "Run continuously while the Dashboard is open" option puts on a server.

    At what kind of rate is this option working?

    When that options enabled, the plugin will make an AJAX request every ~30 seconds that checks if the background task that processes posts/links is running and starts the task if it isn't.

    The server load depends almost entirely on how many unparsed posts and unchecked links you have at any given time. If it's just a couple dozen, the load will be negligible even with that option enabled. If it's thousands, you might notice some performance degradation on weaker servers.

    Anecdotal example : My personal blog runs on a low-end VPS and contains ~4000 links. Re-checking them all in one go has no visible performance impact.

    Thanks whiteshadow.

    My host's server crashed because a log file got overfilled with POST PAYLOAD related errors orginating from requests by you plugin.

    It's not the server load that caused the problem, but Broken Link Checker was indeed making requests every second or two, which caused the log file to inflate rapidly since the server setup was such that each request generated an error.

    Switching to hourly check seems to have solved the problem on my side and my host changed some things on his side too, so I think we got things under control now.

    Anyone can give me their opinion on this :

    is my host in his right to blame me when his log file crashed the server because it got too big?

    It's far from clear that the errors were due to something wrong with the plugin vs a server-side config file requesting for a filter that wasn't activated.

    My point is : isn't it my host's responsibility to manage his log files so that they don't crash the server by becoming too big for whatever reason?

    Since log files are meant to faciliate troubleshooting, isn't absurd that they crash a server at all?

    I'm seriously considering changing to another host.
