Tried to install this via the GUI without success. First time I ran it, got an error complaining "/usr/local/zenoss/zenoss/Products/ZenPacks.zenoss.HttpMonitor-2.0.1-py2.4.egg" wasn't a directory (it was looking for a file below that level). So I created the directory and re-ran the install. It then gave an error complaining "/usr/local/zenoss/zenoss/Products/ZenPacks.zenoss.HttpMonitor-2.0.1-py2.4.egg" was a directory. Couldn't win, gave up.

Hi there, had the same issue.

If you unzip and use the egg file in stead, everything works perfectly ...

hope it helps.

This has not been working for me. If anyone can point out what I am doing wrong, I would be much obliged!

I'm running Zenoss 2.5 in their pre-packaged VMware image.
I unzipped and then via webgui, installed ZenPacks.zenoss.HttpMonitor-2.0.1-py2.4.egg - no errors.
I bound the template to \devices\Ping
I created a local copy on a test monitor I have. Here's a screenshot.
I configured the local copy by editing the "Url" value. Screenshot.
I waited 10+ minutes (Zenoss is using all the default intervals). Still have broken graphs. Screenshot.

Check your zencommand.log file in $ZENHOME/log/ for errors. You may also toggle debugging with "zencommand debug" to get additional logging in the file.

What command am I looking for? I don't see any defined in the template, and after watching the zencommand log tail by for awhile I am not seeing anything that appears related to the http monitor.

RE: Http Monitor

community@zenoss.org — Fri, 30 Jul 2010 03:49:53 GMT

I'm pretty sure the call is "check_http".

RE: Http Monitor

community@zenoss.org — Fri, 30 Jul 2010 04:17:43 GMT

"check_http" not found anywhere zencommand.log. It's been in debug mode for 30+ minutes.

When I grep by device names to which this template is applied, I get nothing relevant to the http monitor zenpack. I see other things (like check_ping) but nothing about http.

I'm beginning to suspect something is missing in the py2.4 version? Screenshot of template page

This is interesting: seems that about the same time I added the http monitor zenpack, the nagois checkping zenpack stopped updating graphs! Although I do see the check_ping command running (apparently without error) in zencommand.log

EDIT much later: I feel bad about this, but a reboot solved it.

Is there a trick in Zenoss 3.0.2 to monitor shared websites or web pages on servers that are already monitored as linux servers having the same IP as the webserver? When adding a new website I get an errror: "Found IP '<x.x.x.x>' on device '<nnn>'; skipping discovery" and consequently the graphs are empty. Having lots of websites on several shared servers, HTTP monitoring with Zenoss is useless for us as it is. :-(

Is it possible to count size, respond time from the displayed Pictures, flashes ... in the monitored site too?

I think it is only the html code are counted?

Would it be possible to have proxy authorization added to this, I have tried to use the basic (-a) authorization and see from some captures that it is not the same as proxy auth.

Would really be helpfull or if someone konws a different way to do thi I would greatly appreciate it.

thanks

Would it be possible to include the search string in the check_http output so its clear in the event what the search string was ( looks as if Nagios did patch the command to do this http://sourceforge.net/tracker/?func=detail&aid=2999924&group_id=29880&atid=397599 ), I get the 'HTTP CRITICAL - pattern not found' text but then have to go back to the device, template to check what the search pattern was!

RE: Http Monitor

community@zenoss.org — Fri, 17 Jun 2011 15:19:55 GMT

Paul, this would be possible by modding the zenpack code. Maybe do some grep'ing for where that 'pattern not found' error is generated. Also find the location where the command and its options are run from and add in the -o and collect the output from it. Then, place the new check_http bin from nagios in place and try getting its -o output to pass over to the event. You'll have to know python and understand how this ZenPacks code does what it does. Otherwise, there is not an easy way to do this.

If you figure it out, let us know and it would be good to submit the code via the bug system for possible inclusion into zenoss proper.

I am having the same problem as you. Multiple virtual hosts on 1 server with 1 IP but can't monitor all of the sites because they resolve to the same IP. Any help anyone?

RE: Http Monitor

For this issue did this ‘hack’

another hack is to use new device name, then rename and blank the ip address to use dns

* see http://community.zenoss.org/message/22597#22597

* will use this method for now...

* Note added an /HTTP/no-ping class, set zproperty zPingMonitorIgnore=True and moved all web servers with a duplicate ip address to a device in /HTTP to this class (so we only ping one ip address, not the same ip address n times)

RE: Http Monitor

community@zenoss.org — Mon, 17 Oct 2011 14:27:34 GMT

I am running Zenoss 3.2, none of those work. I can rename but once I try and blank the IP to use DNS, I get an error.

Moving all of my webservers under /HTTP without being pinged isn't realistic in my environment.

Anything else to try?

RE: Http Monitor

community@zenoss.org — Mon, 17 Oct 2011 14:30:32 GMT

We’re currently on 3.1, so sounds as if the hack is no longer available at 3.2

See the below how-to I made a while back. The 'trick' is creating multiple datasources on a single local template.

It was written for an older version of Zenoss, but it should still generally apply. Enjoy!

@nick, I wasn't aware of this solution, works like a charm on 3.2. Thanks a lot!!

alright, was annoyed by the inability to go through an Authenticated proxy, so i copied the code in each of the files where it says basic Auth user, and basic Auth pass and changed them proxyAuthuser, proxyAuth pass. the main thing to remember is in the datasources/HttpMonitorDataSource.py when you do the copy and then modify, change it to append -b instead of -a . -b option is in the newest version of check_http for nagios. What i ended up doing was download the tar.gz file, extracted, then compiled using configure, make. Afterwards, i copied the check_http from nagios and put in under my zenoss/libexec location. From the Zenoss box, i tested by opening up a terminal and going to my zenoss/libexec location and ran ./check_http -I (proxyip) -b username:password -u (url to check). Maybe Zenoss can get the latest check_http added in their next release? I would make a zenpack but im just learning myself here with this.... Anyways, hope this helps.

Hey, i found a way to monitor smtp server with check_http

check this:

nano -w /usr/local/zenoss/zenoss/ZenPacks/ZenPacks.zenoss.HttpMonitor-2.0.3-py2.6.egg/ZenPacks/zenoss/HttpMonitor/datasources/HttpMonitorDataSource.py

edit - change

if self.port:

if (self.port == 25):

parts.append('-e 220 ')

parts.append('-p %s' % self.port)

at getCommand fuction.

so in your template set port to 25 and your ip/name would be something like smtp.gmail.com or its ip..

check it.. bye

What are the units for the two graphs Time and Size. I'm assuming time is milliseconds, but what is bytes?

RE: Http Monitor

community@zenoss.org — Thu, 07 Jun 2012 16:58:44 GMT

Sorry for the double posting, but posted this on the user forum also before I realized I should have posted here.

We're running Zenoss 3.2.1 on SUSE

I've been having problems with using the HTTP Monitor Core Zenpack regular expressions to monitor specific content. From what I can tell after hours of trial and error, if the regular expression has a dollar sign in the expression, the changes will not push out to the collector. I know it's not pushing out because each time I make a change to the http monitor local template, I change the severity. If I see the previous severity value on the alert I know the change did not make it to the collector. I'm simply trying to use the following regex to scan for a valid hex string on a web page.

^[0-9A-Fa-f]{30,}$

I believe there are also problems with the comma.

The strange thing is that if I test it with check_http it works perfectly as expected.

does the $ sign need to be escaped?

thanks!!

P.S. The severity pull down is also off by 1. When you set the Severity on the template to "Info", the alert event displays as a Warning, and when you set to Error, the event is set to Critical.
