You can find a py2.6 version for Zenoss 3.0 from here: http://dev.zenoss.org/zenpacks/

Please report back if it works and we'll update the listing.

Hi,

There's a bug or incompatibility of some sort between my version of Redis and the 3.0-compatible zenpack.

My version of redis is 2.2.11.

INFO returns:

allocation_stats:6=1,7=1,8=20,9=44,10=34,11=61,12=5,13=35,14=24,15=63,16=10084,17=12,18=6,19=16,20=9,21=7,22=5,23=20,24=127,25=3,26=3,27=3,28=4,29=4,30=1,31=1,32=7,34=1,36=1,37=4,38=1,39=4,40=2,43=2,45=1,48=12,49=1,53=1,56=4,57=3,58=1,59=2,60=1,62=1,63=1,64=4,65=2,66=2,68=1,69=3,70=1,71=3,72=5,73=2,74=1,76=1,77=1,78=3,79=2,80=6,81=1,82=9,83=3,84=7,85=8,86=13,87=4,88=73,89=5,90=4,128=2,>=256=11

That >=256=11 on the end of the string breaks client.py.

I git cloned the repo and did a setup build;setup install. The install fails with this message:

error: file '/home/zenoss/git/ZenPacks.chudler.redis/build/bdist.linux-x86_64/egg/ZenPacks/__init__.py' does not exist

I made the dirs and touched the file and it fails again with another missing __init__.py along a similar path. After doing mkdir and touch several times I gave up. I really would like to make this work.

I am running python 2.6 with zenoss 3.2.1 on Ubuntu 10.10. Upgrading at this time really isn't an option at this point.

I was running python setup.py -n install to get this message.

Just for curiosity I ran setup.py with out the -n and it installed. But when I ran the zenpack --install it failed again:

hmm. I just did a quick test on dev vm, and the egg installed OK.

Your output shows its installed (albeit broken). Can you run the following as the zenoss user

zenpack --list | grep -i redi

I'm assuming that will produce an entry. If it does then do:

zenpack --remove=ZenPacks.chudler.redis

If you can withstand a little time a full stack restart wouldn't hurt here, but might not be necessary.

As the root user:

service zenoss stop
ps aux | grep -i zenoss

Kill any processes that might be stuck. then

service zenoss start

If you can't take the downtime, jump skip the above to snippets, and jump right here. Now try re-installing the pack from the downloaded link I sent you.

RE: Redis Monitor

community@zenoss.org — Sat, 13 Oct 2012 00:13:48 GMT

Ok, I figured out what was wrong. When I did a zenpack --list, there was a path under python2.6:

ZenPacks.chudler.redis (/usr/local/zenoss/python/lib/python2.6/site-packages/ZenPacks.chudler.redis-1.0.1-py2.6.egg)

I did the remove and then rm -rf on that path. Finally doing an install with the egg you sent me. All good now.

RE: Redis Monitor

community@zenoss.org — Sat, 13 Oct 2012 00:20:24 GMT

That path under site-packages was a left over from playing with the git source.

Thank you for your help!

Hi Matt,

Is there some way to monitor multiple Redis-server instances ??

Don't know the real way of submitting a bugfix, so here goes.

I had a problem with my redis-monitor giving me errors all the time when parsing the info command from redis, I noticed in the sourcecode that there were no ensuring that the input read was as expected, therefore I have created the following fix:

--- a/ZenPacks/chudler/redis/lib/redis/client.py
+++ b/ZenPacks/chudler/redis/lib/redis/client.py
@@ -126,7 +126,10 @@ def parse_info(response):
                 sub_dict[k] = v
         return sub_dict
     for line in response.splitlines():
-        key, value = line.split(':')
+        try:
+            key, value = line.split(':')
+        except ValueError:
+            continue
         try:
             info[key] = int(value)
         except ValueError:

this will simply prevent the check_redis.py script from crashing when the line read doesn't contain a colon.
