Having made my XWiki site available to other users, I was concerned to find that the site
became unusable at one point with client connections eventually timing out. I had no way
to diagnose the problem, but eventually I managed to make a (slow) SSH connection to the
server and restarted Tomcat, and things seemed to settle back to normal.
The problem is I have no real sense of what happened and how to prevent it happening
again. To that end, I'd appreciate any suggestions for monitoring the server and
diagnosing poor performance. What do others typically use? I have an Apache2 server
passing wiki page requests to Tomcat7 via an ajp connector, and a PostgreSQL database. My
guess is that Tomcat is doing most of the work here so that's probably what I need to
monitor the most.

I's also find any suggestions very helpful, I've had that happen a few times and
outside of monitoring CPU and RAM, I've found logging to be difficult to use and
configure, and even when I get it configured it's not very helpful.

Hello all,
Here's my experience at monitoring XWikis.
With i2geo.net and with my private XWiki, I use a zabbix server.
This php-based monitoring tool is quite easy to configure for http monitoring and with a
few more steps you get a mail notification when, e.g., a timeout occurs in connections.
I've been using HypericHQ for a while, a java based monitoring, which was rather nice
to manipulate but a machine-name-change broke everything, so I looked for something a tick
more modern.
At curriki.org, a site with lots of visitors, there's quite a few tools used to
monitor.
- First, for the safety and honesty of a system outside, alertsite.com is used. It is very
effective at detecting breakges, including potential internet backbones'. We use
monitoring from three locations.
- Second, because, indeed, the XWiki servers sometimes need a push, there used to be a
regular script that checks a basic page and, if failed, auto-restarts the app-server. For
us, this is a bit unsafe because we like to control things after a restart.
- Third, for a while, we have been running a "combined monitoring" which allowed
to combine a small graphical view synced with logs of apache, the app-server,
thread-dumps, and mysql. This allowed to catch "bad actions" which sometimes
happen when power users perform actions which trigger too big queries which locked others
(group-deletions were such an action).
- Finally, we also added a zabbix which collects http monitoring as well as other
"classical" values (disks, memory, apache-stats, …).
The rhythm at curriki is about a week… after a week, one of the two cluster nodes
(there's two currently) needs a restart because some memory gets exhausted and the GC
starts to fail. We generally get alertsite errors then.
The interest of running a monitoring infrastructure such as zabbix, is that you can
analyze the behaviors of multiple variables and see if there is a way to predict if things
are getting wrong. It remains a guts' feeling story but still gives you quite some
confidence.
It would be really nice if we could converge on a set of JMX analysis "items"
for zabbix so that we could be analyzing more concretely the xwiki-relevant information
(in particular the cache behaviors) and start adjusting to less fall out of memory.

Hi Paul,
Many thanks for your contribution. I'll certainly look into Zabbix, although I must
confess to being aghast at what appears to be a large and complex tool for what I'd
hoped was quite simple. I hadn't realised these servers were so temperamental. Before
I loose myself in getting acquainted with a new sophisticated product, could you tell me
whether Zabbix (or something else) will help me identify the following?:
- When are users suffering timeouts (doesn't have to be real time, happy to check
summary later)
- Where was the timeout occuring (network, Apache, Tomcat, Postgres)
- What was the cause of the timeout (too many connections, low memory, long Java
operation, long query, etc)
- What specific item (Java program, DB query) was responsible
I wonder whether all this should be discoverable in the logs, with the right
configuration.
I've seen a lot of mention of JMX for Tomcat monitoring, but I've shied away from
it since I wanted to start simple, but perhaps there is no simple ... ;-(

Bryn,
without JMX, straight and simple console output and thread-dump based… that's what the
monitor-sample tool was doing, it has a potential to answer the back-end of that (e.g.
DB-queries). In particular, it is the only one that can express the query being hanging
and this is exactly what was needed for us.
JMX is a simple way to communicate to the internals of the java process. Standard things
are typically delivered with JMX (e.g. the heap size).

Yes, you'd get that with the tomcat connection time or apache workers.
- Where was the timeout occuring (network, Apache,
Tomcat, Postgres)
That's a tick more delicate since one timeout creates others...
- What was the cause of the timeout (too many
connections, low memory, long Java operation, long query, etc)
You really can't disambiguate this so clearly.
But you can see the amount of connections the heap memory or the amount of active threads
with JMX. That helps you in this direction, I think.
- What specific item (Java program, DB query) was
responsible
I wonder whether all this should be discoverable in the logs, with the right
configuration.
The DB query I could only get with the combined log monitor… but if you can get warned by
zabbix, then you can run a "get full processlist" from mysql.
FWIW, the combined monitor is at
https://github.com/xwiki-contrib/xwiki-clams-core/tree/master/tools/appserv… but
it is likely to be very specific to our installation (e.g. it requires key-based ssh).
I've seen a lot of mention of JMX for Tomcat

Hi Bryn,
There are some information that I’ve put
at http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Monitoring to monitor XWiki
instances.
JavaMelody is quite great for that but it won’t send you alerts.
Make sure to check the tools at the end in the Others section too. There’s the xinit tool
which is a monitoring/admin tool developed by XWiki SAS.
Hope it helps,

Btw,
I am not sure you could say the XWiki installs are that "pesky".
However, depending on the user base, it may really need quite some tuning.
For example, if your xwiki manipulates complex documents the document cache may be too big
for the memory, and that you only reach with some time (it could be a week or two).
OutOfMemoryErrors then appear on a regular basis.
Another example has been the amount of registered users. This is a bit too much on curriki
to store into a page of objects, so special treatment has been applied.
Yet another example would be the mass of attachments, e.g if people use this as a shared
disk, where the file-system-attachments solution has helped quite many (I think).
I think all wikis and CMSs that I know of are rather limited in their default goals
(beyond XWiki, I have experience with Drupal and Wordpress) and special treatment maybe be
quickly available, in config, install, or custom development.
Monitoring tools can help you adjust this.
Bryn, maybe you want to indicate how big is your system?
Maybe it's just a matter of some too eager clients (e.g. some ever repeat
javascript-based-requests served to tens of users every second or so)?
paul

BTW if you have setup some tools and have had successes with them to monitor xwiki

(Sorry for top-posting - I'm stuck with Outlook Live :-(
My system's very small - approx 20 users and very little content at present. It's
for a small collaborative research group which may grew to ~100 members. I expect quite a
few largish attachments and have already configured filesystem attachments.
I'm using PostgreSQL for various reasons, so can't add all the suggested indexes
(names the string prefix ones that are specific to MySQL), but I'd be surprised to be
hitting limits so soon.
The slowdown occurred soon after I opened the wiki to the other members, who probably did
some exploring and perhaps triggered something painful.

You definitely need to explore when it happens.
- something such as show full processlist (that's a MySQL thing) should be available
to show if there's an SQL query taking long and if others are slow (typically, big
LIKE queries tend to block all writes)
- invoke a thread-dump (kill -HUP or use JMX or
http://extensions.xwiki.org/xwiki/bin/view/Extension/JMX+Access#HExample5:g…):
the threads generally carry the path of the http requests
- check memory
- make sure you enable -verbose:gc as a JVM option to indicate when memory limits are
reached

Limited memory?
Well I'm running everything off a single VM configured with 8GB RAM and 2 VCPUS. If
necessary I can use more VMs but I wanted to keep things simple until I knew what my
actual performance needs were. I also have access to plenty of persistent storage.
I have Tomcat configured with CATALINA_OPTS="-server -Xms800m -Xmx800m
-XX:MaxPermSize=196m"

I've seen rather often that things are more battle-tested for MySQL.
But I fully agree you have reasons to prefer PostgreSQL.
Yes, and I'd be interested to look into optimising common searches once things have
grown and I understand the query workload. Alternatives to MySQL string prefix indexes
would be GIN or GIST - the pg_trgm package looks promising.

New subject: [xwiki-users] Question regarding AppServerTrustedAuthServiceImpl
To know if you are authenticated from XWiki point of view look at the
top right corner, you should see you name or id there (so probably
jsmith here). If you are not authenticated then you should have a
"login" button/link instead.
You can also enable debug log for this authenticator. Search for it in
Administration -> Logging and set log level to TRACE or DEBUG. When
this is done you should see details on what is happening in this
authenticator in your application server log.

You are mixing several things here. All the actual authentication work

This is not a XWiki question, the authentication is done by whatever
authenticator you are using in fron of XWiki.
AppServerTrustedAuthServiceImpl just trust it.

realm. AppServerTrustedAuthServiceImpl seems to my option. Are there some detailed
documents or examples for using it?
yes: add a line do the xwiki.cfg in the WEB-INF folder, as explained here:
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Authentication#HContain…
That (and restarting tomcat) should be everything you need to do.
Cheers,
Clemens

New subject: [xwiki-users] Question regarding AppServerTrustedAuthServiceImpl
Hi Thomas,
Thanks for your help.
Are you saying that the Tomcat JDBC realm users will be automatically becoming registered
xwiki users if AppServerTrustedAuthServiceImpl is turned on. Should we see all the users
in realm in the xwiki user list if AppServerTrustedAuthServiceImpl is configured
correctly?
Thx again.

To know if you are authenticated from XWiki point of view look at the top right corner,
you should see you name or id there (so probably jsmith here). If you are not
authenticated then you should have a "login" button/link instead.
You can also enable debug log for this authenticator. Search for it in Administration
-> Logging and set log level to TRACE or DEBUG. When this is done you should see
details on what is happening in this authenticator in your application server log.

AppServerTrustedAuthServiceImpl will create a user as soon as its
accessing XWiki so yes it's automatically registered but no you won't
see all users, only those that conected to XWiki.
Thx again.

New subject: [xwiki-users] Question regarding AppServerTrustedAuthServiceImpl
Thomas,
1) The logging level is set to be trace for all by default, but I don't see where
anything regarding authentication in any of the log file in TOMCAT/logs directory (
catalina.out is the stdout log )
2) If I do the following:
-- logout from xwiki from browser
-- Keep log out
-- put URL http://techdev1:9090/XWiki/bin/view/XYZ/ into browser <== this is protected
by realm
-- return
-- immediately getting 403
Question: why I am not getting log-in prompt?
Thanks,
Ji

No the level is not set to trace by default. The level is what you
have in the "Level" column and by default it's not set for most of
them (which means it's the default which is INFO).
2) If I do the following:

Again this has absolutely nothing to do with XWiki, XWiki is not doing
anything here it's whatever authenticator YOU setup in front of XWiki.
AppServerTrustedAuthServiceImpl just received the user id once the
actual authentication is validated and you finally ends up on XWiki.
