[Profiling] How to profile/tune Solr server
Hi All,
I am a solr newbie. I find solr documents easy to access and use, which is
really good thing. While my problem is I did not find a solr home grown
profiling/monitoring tool.
I set up the server as a multi-core server, each core has approximately 2GB
index. And I need to update solr and re-generate index in a real time
manner (In java code, using SolrJ). Sometimes the update operation is slow.
And it is expected that in a year, the index size may increase to 4GB. And
I need to do something to prevent performance downgrade.
Is there any solr official monitoring & profiling tool for this?

SolrMeter is useful too, it can be plugged to a production server just
to watch evolution of caches usage :

Hi Spark,
2009 there was a monitor from lucidimagination:
http://www.lucidimagination.com/about/news/releases/lucid-imagination-releases-performance-monitoring-utility-open-source-apache-lucene
A colleague of mine calls the sematext-monitor "trojan" because "SPM phone home":
"Easy in, easy out - if you try SPM and don't like it, simply stop and remove the small client-side piece that sends us your data"
http://sematext.com/spm/solr-performance-monitoring/index.html
Looks like other people using a "real profiler" like YourKit Java Profiler
http://forums.yourkit.com/viewtopic.php?f=3&t=3850
There is also an article about Zabbix
http://www.lucidimagination.com/blog/2011/10/02/monitoring-apache-solr-and-lucidworks-with-zabbix/
In your case any profiler would do, but if you find out a Profiler with solr-specific default-filter let me know.

Re: how to transform a URL (newbie question)
Posted by Erick Erickson <er...@gmail.com>.
I think you're confusing Solr with a web app <G>....
Solr itself has nothing to do whatsoever with presenting
things to the user. It just returns, as you have seen,
XML (or JSON or ....) formatted replies. It's up to the
application layer to do something intelligent with those.
That said, the /browse request handler that ships with the
example code uses something
called the VelocityResponseWriter to render pages, where
the VeolcityResponseWriter interacts with the templates
Erik Hatcher mentioned to show you pages. So think of
all the Velocity stuff as your app engine for demo purposes.
Erik is directing you at that code if you want to hack the
Solr example to display stuff.
Hope that helps
Erick (not Hatcher <G>)

Erik,
OK, I will look at that. Basically, what I amtrying to do is to index a
document with lots of URLs. I also index the url and give it a field type.
Don't know much about solr yet, but though maybe I can transform the url to
an active link, i.e. '<a href>'. I tried putting the href into the xml
document, but it just prints out as text in html. I also could not find any
xslt transform or schema.
thanks

Ben,
Not quite sure how to interpret what you're asking here. Are you speaking
of the /browse view? If so, you can tweak the templates under conf/velocity
to make links out of things.
But generally, it's the end application that would take the results from
Solr and render links as appropriate.

I am a beginner to solr and need to ask the following:
Using the apache-solr example, how can I display an url in the xml document
as an active link/url in http? Do i need to add some special transform in
the example.xslt file?
thanks

Hi,
There are no official tools other than looking at the built-in stats pages and perhaps using JConsole or similar JVM monitoring tools. Note that Solr's JMX capabilities may let you hook your enterprise's existing monitoring dashboard up with Solr.
Also check out the new monitoring service from Sematext which will give you graphs and all. So far it's free evaluation: http://sematext.com/spm/index.html
Do you have a clue for why the indexing is slow?
