  • do you happen to have experience with setting up influxdb and telegraf? or maybe something else that might be better suited?

    the metrics are currently in prometheus metrics format and scraped every 5 minutes.

    my idea was to keep the current retention for most metrics and have longer retention (possibly with lower granularity for data older than a month).

    the current prometheus setup is super simple, you can see (and older copy of) the config here.

    if you want to build a configuration for influxdb/telegraf that i can more or less just drop in there without too many adjustments that would certainly be welcomed.

    the metric that would need longer retention is lemmy_federation_state_last_successful_id_local.














  • Except it wasn’t created on lemmy.ml, it was created on lemmy.world.

    lemmy.world then informed lemmy.ml that it is intended to be published in the community that it was created for.

    It doesn’t say “crossposted from lemmy.world” but “crossposted from canonical_post_url”. This is not wrong in any way, although it might be a bit confusing and could likely be improved by including a reference to the community. The instance domain should for the most part just be a technical detail there.

    It should also be noted that this format of crossposting is an implementation detail of Lemmy-UI and other clients may handle it differently (if they’re implementing crossposting in the first place).


  • I’m not saying it’s technically impossible, although it would likely be a bit challenging to integrate on the technical level, as the community instance has no authority to modify the post itself other than removing it from the community at this point.

    The existing fedilink is already present for technical reasons anyway, so this is currently only showing existing data.

    Why would you want a lemmy.ml link though? On Lemmy you’re typically intending to stay on your own instance, which many third party apps already implement. For Lemmy UI there is already a feature request to implement this, although it might still take some time to get done. If you have the canonical link to an object (which will always point to the users instance) Lemmy can look up which post/comment you’re referring to in its db without any network calls when it already knows about the entry. If you were linking to the lemmy.ml version of that post then the instance would first have to do a network request to resolve that and then it would realize it’s actually the lemmy.world version that it may or may not know about already.


  • it doesn’t matter whether you consider it reasonable, as it’s this way for technical reasons.

    when a post or comment are created they are created on the users instance. the users instance then tells the community instance about the new post/comment and the community instance relays (announces) this to other instances that have community subscribers.

    the fedilink is an id and reference to the original item. this unique id is known to all servers that know about this comment and it is what is used when updates to the post are distributed. except for the reference to the item on the originating instance, no instance stores information about where to find a specific post/comment on a random other instance.



  • It should be noted that the (visibility of) community bans are a result of better enforcement of site bans in 0.19.4, which for now is implemented by sending out community bans for local communities when a user gets instance banned: https://github.com/LemmyNet/lemmy/pull/4464

    Prior to this, when a user got instance banned from .ml, they were also implicitly banned from .ml communities, but this was only known to the instance they were banned on. As a result, users were still able to post, comment, and vote on those communities, but it would be visible only on that user’s instance, not federated anywhere else. Visibility of this ban was exclusively on the banning instance’s modlog.

    fyi @SpaceCadet@feddit.nl


  • 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.
