I'm not sure what we do with z=16-18, I would say we do this like in the past.

Peter wrote a little tool to show the replag: http://toolserver.org/~mazder/tirex-replag/?refresh=0&human=1 So we have now a replag of 4 days and I would say we need 3 days to be up-to-date. Unfortunately is munin-graph again out of order: http://munin.toolserver.org/OSM/ptolemy/replication_delay2.html and jira-request TS-1125 after nearly a month still untouched. :-( I believe it would be difficult for us to keep the wiki up-to-data, so let's use this list. But I know that's not the optimal medium if somebody is coming for a long vacation or so, so it's not the problem that you ask.

I start to rendering all tiles z=9-18 systematically, that are watched in the last 64 days and older than 3 days (because expire didn't work a long time). I put additional z=16-18 in the batch because it is else difficult to handle in different processes. We rendering 150-200 tiles/min what is really nice. There are 3 Mio. tiles in the batch so it will need around 11 days. After this we need to re-render only tiles that are older than a year because expiring is again working, so there will be than much fewer tiles to handle.

The queue is sorted by the number of requests received for this tile, not by age. when tirex receives a dirty message from mod_tile (metatile oder then planet-timestamp), it enqueues it with prio 2, so it's put into the systema bucket. This can be changed in source [1] (i guess the second int in the array is the priority for cmdRender). Also, if you enqueue a tile that is already in one of the queues, it's not added a second time but just moved up a little in the queue.

Will this not quickly mess up the systematic ordering of the systema queue? Is it possible to turn off this reordering? Has this got something to do with that throughput has dropped from 160 - 200 down to (still better than before) 60 - 70 tiles / minute? But overall, it does seem the systematicity is working. Perhaps the mappings from mod_tile render request types to tirex priority levels could be made configurable. Alternatively, one could tune the mod_tile config to send requests as cmdDirty rather than cmdRender (the latter assumes the request can be rendered on the fly, which isn't the case if about 300k tiles are ahead of it in the queue) mod_tiles cmdDirty maps onto tirex prio level 10 by default. Kai P.S. In the run.log file, at the end of each import, there are messages of the form 26799 import done [2011-08-29 02:11:54] 26799 expiring tiles [2011-08-29 02:11:54] 26799 [error] tile_expiry error [2011-08-29 02:11:55] 26799 resetting state Does the "resetting state" have anything to do with that the replag is not going down? ------------------------------ Message: 11 Date: Mon, 29 Aug 2011 21:36:07 +0200 From: Tim Alder &lt;tim.alder(a)s2002.tu-chemnitz.de&gt; Subject: Re: [Maps-l] Starting of re-rendering all tiles To: Map integration &lt;maps-l(a)lists.wikimedia.org&gt; Message-ID: &lt;4E5BEA27.8040006(a)s2002.tu-chemnitz.de&gt; Content-Type: text/plain; charset=ISO-8859-1; format=flowed Am 29.08.2011 16:40, schrieb Kai Krueger: Hello, my theory is that we started with rendering around Alaska. This area is relative empty and stretched by mercator-projection. Now we are somewhere in Canada/USA incl. NYC with high density of geo-objects. Following the z-curve we should come back to empty areas in the north several times, and render again very fast. If not, my theory is false. In general: Tirex should be able to order the queue by z-curve, especially if you have more than one style (not sure how it can reach the end of it), it would makes it for me much easier to handle it. And Tirex should be able to not order the queue. I change the parameter to 4 in ~/tirex/lib/vendor_perl/5.12/Tirex/Source/ModTile.pm It seems that it need a restart of tirex, what I don't want to do in the moment. No idea where to do this. Would be important to know. It seems to work at beginning. ------------------------------ _______________________________________________ Maps-l mailing list Maps-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/maps-l End of Maps-l Digest, Vol 28, Issue 4 *************************************
