I highly recommend a version selector in the header! I am *always* landing on 6.x docs from google. On Tue, Apr 28, 2020 at 5:18 PM Cassandra Targett wrote: > > In case the list breaks the URL to view the Jenkins build, here's a shorter > URL: > > https://s.apache.org/df7ew. > > On Tue, Apr 28,

Solr Ref Guide Redesign coming in 8.6

The PMC would like to engage the Solr user community for feedback on an extensive redesign of the Solr Reference Guide I've just committed to the master (future 9.0) branch. You can see the new design from our Jenkins build of master: https://builds.apache.org/view/L/view/Lucene/job/Solr-reference

Hi all - I'm running this query on solr cloud 8.5.1 with the index on HDFS: curl http://enceladus:9100/solr/PROCESSOR_LOGS/update?commit=true -H "Connect-Type: text/xml" --data-binary 'StartTime:[2020-01-01T01:02:43Z TO 2020-04-25T00:00:00Z]' getting this response:   1   500   54091  

Re: Which Solr metrics do you find important?

I also have some Python that pull stuff from clusterstatus and sends it to InfluxDB. We wrote a servlet filter that intercepts requests to Solr and sends performance data to monitoring. That gives us per-request handler traffic and response time percentiles. Telegraf for CPU, run queue, disk I

Re: 'velocity' does not exist . Do an 'create-queryresponsewriter' , if you want to create it

Try add-queryresponsewriter instead of "update" - it's not currently defined so there's nothing to update. Add it first, but also make sure you've got the Velocity contrib and dependencies wired into your configset as well. Erik > On Apr 28, 2020, at 9:15 AM, Prakhar Kumar > wrote:

What version of Solr? Velocity was moved to a contrib recently. To prevent it, one of: - add a lib directive in solrconfig.xml to the velocity directory - don’t tty to go to the /browse endpoint Best, Erick > On Apr 28, 2020, at 9:15 AM, Prakhar Kumar > wrote: > > Hello Team, > > I am gettin

Re: Which Solr metrics do you find important?

I think clusterstatus is how you find some of that stuff. I wrote this when I was using datadog to supplement what they offered: https://github.com/msporleder/dd-solrcloud/blob/master/solrcloud.py (sorry for crappy python) and it got me most of the monitoring I needed for my particular situation.

Re: Which Solr metrics do you find important?

Thanks a lot, Matthew! OK, so you do care about the size of tlogs. As well as Collections API stuff (clusterstatus, overseerstatus). And DIH, I didn't think that these stats would be interesting, but surely they are for people who use DIH :) Best regards, Radu -- Monitoring - Log Management - Ale

Hello Team, I am getting this weird error in Solr logs. Does anyone know how to prevent it from happening? ERROR:[{ "update-queryresponsewriter":{ "startup":"lazy", "name":"velocity", "class":"solr.VelocityResponseWriter", "template.base.dir":"", "solr.resource.l

Which Solr metrics do you find important?

Hi fellow Solr users, I'm looking into improving our Solr monitoring and I was curious on which metrics you consider relevant. >From what we currently have, I'm only really missing fieldCache. Which we collect, but not show in the UI yet (unless you a

Re: On the delay in electing a leader when the leader is dead(Solr 7.5)

There are some additional things I'm curious about. When I tested it in the development environment, I found that setting the commit interval to 15 seconds was sufficient to select a leader.(Thank you.) But if you commit every 15 seconds, doesn't it remake the "Searcher" each time and clear the qu

Sorry about the late reply. The faceted search and free text search query performance degraded for us. Thanks, Rajeswari On 4/23/20, 12:21 AM, "Srinivas Kashyap" wrote: Can you share with details, what performance was degraded? Thanks, srinivas From: Natarajan, Rajeswari
