I cant seem to get timely post federation to my instance (moist.catsweat.com) from lemmy.world. I might see a new post every few hours instead of every minute or so.

posts from other lemmy instances (lemmy.ca, lemmy.ml, dbzer0, etc) have no problem.

i see a ton of lemmy.world traffic in my nginx logs… it seems very specific to ‘new posts’. voting/comments seem to come through no problem once the post shows up.

ive checked a few other instances similar to mine, and they are not having this issue. so it seems something specific to lemmy.world and my instance.

i do recall a similar issue several months back, and it involved a lemmy.world admin resetting some outbound queue.

any ideas?

    I can’t tell you why you’re lagging but you’re clearly lagging quite a bit behind.

    which country is your instance located in?
    did you (or someone else on your instance) recently subscribe to a bunch of high traffic communities on lemmy.world, which would make lemmy.world send more activities to you?

    lemmy by default only sends activities in a community to another instance if there’s at least one subscriber to the community on that instance. if you’re located far from finland, where lemmy.world is located, you might have been able to keep up just enough before this, although this isn’t the first time as the graphs above show.

      Hey, sorry for the late reply, but I’m trying to figure out who runs this graph, because if it needs something like a bit of funding to store data for longer periods I’d like to help. Do you know, or know where you heard about it?

        Hi, I run this.

        What benefit do you expect from longer retention periods and how much time did you have in mind?

        The way data is currently collected and stored keeps the same granularity for the entire time period, which currently uses around 60 GiB for a month of retention across all monitored instances.

          Mainly, I’m interested in how Lemmy is growing and changing as a whole. If there was a way to store activity just weekly or even monthly that would help.

            so all you’re looking for is the amount of activities generated per instance?

            that is only a small subset of the data currently collected, most of the storage use currently comes from collecting information in relation to other instances.

                I’ll probably have to look at another storage than prometheus, aiui it’s not really well suited for this task.

                maybe something with influxdb+telegraf, although i haven’t looked at that yet.
