Best OSS Systems Mgmt App You Never Heard Of 109

FLOSSisnot4Teeth writes "You probably are familiar with Nagios and Webmin as two of the most widely deployed open source systems management applications. However, this month's Project of the Month is probably a newcomer to open source systems and network administrators. Zenoss Core is a systems monitoring platform, released under GPL and over the last year it's become one of the most popular projects. Unlike most of these new "commercially backed" open source projects, Zenoss Core is the only version, their corporate sponsor doesn't offer a "pro version". Also their developers have been committing code back to other projects like RRDTool and Twisted. I have been playing around with Zenoss for about six months and have been totally impressed. Would be curious to see what other Slashdot readers think." and Slashdot are both owned by OSTG.

    This seems a bit reminiscent of AdventNet's OpManager system. I would like to point out right now, though, that OpManager is about 700$ for a decent license that even compares to the kind of coverage you get from Zenoss. I wouldn't compare this app to Webmin so much; webmin controls only local system programs and some minimal enterprise software. This dives into the devices end of things as well, providing a decent number of MIBs. I'm very impressed by how the management console includes inventory on devices. Documentation seems decent, but then again I've been working with enterprise networking and systems management for several years. Even at that, this tool isn't demeaning to those who have prior experience. All and all a great OSS project and I look forward to seeing it continue to improve with time.
    • by muszek ( 882567 )
      I just briefly looked at what Zenoss does... not what I was hoping for. I see a great need for FOSS web server management software. Some neat tools that would make configuring various services (apache, postfix, bind, vsftpd, sshd... stuff like that) easier for newbies. I've had my own dedicated server for a year now and still there are areas that I'm lacking at. I wanted to go 100% FOSS, so didn't get any proprietary control panel for that server. I'm using, because I'm scared to touch BIND.

        If you are looking for a tool to configure Apache, Webmin would be the way to go. One of its modules provides a relatively easy to use UI for editing httpd.conf and other Apache config files.

        Plus there are other modules for servers like Sendmail, Postfix, SSHd, BIND, Squid and more..
        • by muszek ( 882567 )
          Yeah, but Webmin doesn't quite make things easier. Looking at BIND module still makes me want to cry. It makes things easier for those that feel uncomfortable with CLI, though.

          What I was talking about is a thing that kinda dumbs everything down, letting users set up the most common things. Example: in Apache few most common options + adding of virtual domains. In BIND, add domains, record type and target address.

          Don't get me wrong, Nagios rocks and has been a godsend, even back in the netsaint era. Where Zenoss is useful is adding new devices for templates that already exist. In Nagios it's either change the underlying config files, pre-flight, and reload, or use a GUI to do the same.

          Our use has transitioned from hand-crafted nagios plugins for bespoke services to more generic checks and longer term capacity planning. Zenoss can do this, and it appears with less operational management, allowing us to focus on performance data and more in-depth Windows monitors (again an internal change from Linux core systems to Windows -- different client base).

    Jan 26, 2007

    I may have finally found the perfect monitor solution for my network: Zenoss. I have been using Nagios + Cacti + Smokeping for quite a while now. It works, but it's not integrated, and for many services, I'm running 2-3 checks. Running those every 5-10 minutes generates a tremendous amount of traffic (during the last 2 weeks, the monitor station has caused 20% of all traffic crossing the primary firewall!). The closest all-in-one I'd found previously was OpenNMS, which is so difficult to really understand and manage well, and so didn't fit my needs. I'd given some thought to rolling my own in Ruby, but just don't have the time for such an undertaking.

    So while browsing the rPath/rBuilder site this morning, I discovered Zenoss. It's Zope-based, which I find a bit interesting. But from what I've seen in the 30 minutes I've had it running, the developers are right on with what I've been looking for. It has auto-discovery support, placing everything into a "/Discovered" group if it can't pick the right group on its own (the firewall was placed into the "/Network/Routers" group since it was part of the discovery chain). But it is smart enough to correlate different IPs to a single device, which OpenNMS can't do. It also supports Nagios plugins (though only via ssh and not nrpe), so I can leverage that investment while I evaluate the Zenoss way of checking.

    There's also a built-in syslog catcher, so it can correlate log events to devices, which could be another huge time saver. And it has asset/inventory management so I don't need to keep that data separately either. What can't this puppy do?!

    You can install from source or RPM, and there's a vmware image available too. It requires Python 2.3.5+ and MySQL 5.0.22+. Since I wanted to run on my Debian Sarge monitor station (which already has access to all the devices to manage), I had to upgrade the DB. Easy enough with the backports. The only trick I ran into there is that the install process requires port 8100 be available. You can change after install, but I couldn't find a way to change prior. The installer doesn't notice if the port is already in use, it just silently fails, and so when starting the Zope DB setup, it gets in a loop of printing "." (dots). Finally realized I had to shut down a Mongrel-run Rails app to get it going, and it worked perfectly. (Bug #933 has been filed.)

    Stay tuned for more, as I will be playing with this ALOT over the next few weeks!

            I'll keep that in mind. I should point out, in case I haven't already, that I'm doing this on my own, to kind of push the project onward, and to make myself look a bit better in the eyes of my superiors. My direct manager is in charge of the overall project.

            I will look more into this later this week though. The bookmarks are already down.

            • To be quite honest, we do all of that via OpenNMS. We also make use of it's paging system to alert techs and/or management when there is a fault - data center temp over/under threshold, server down, UPS fault, UPS on battery, etc. Your monitoring hardware has to be SNMP enabled (add on cards, etc.) but if you can poll it via SNMP, OpenNMS can monitor it.

    I'm using Nagios on a group of core network devices. I have to be super careful not to perform an "up2date" on it (using RH 4.0 EL) because the Nagios packages always overwrite my config files. But Nagios is good, and it's been very useful. It took me a few days of work to get it set up the way I wanted, and it's been a charm ever since.

    A few weeks ago someone posted an article on the top ten OSS projects to watch, and Zenoss was one of those projects. I downloaded it to experiment. I had it up and running in about 20 minutes, on Ubuntu. It's far more powerful at its ability to gather data from nodes. And setup is far less manual. Network discovery worked very well. It found devices on our network that we didn't know were out there. It required no integration with other packages. The interface is also more intuitive in some areas, such as viewing event histories. But, it's more challenging to find performance charts the first few times.

    I especially liked the automatic snmp walk through the MIBS on each device. This makes it much easier to pull statistics from it, without having to edit text files. The MRTG-style charts are also good. I wish they were more readily configurable. I also wish there were more MIBS in the distribution, but you can find most by carefully searching equipment provider's web sites.

    All in all, After running it side by side with my Nagios setup for a couple of weeks, I like it much better. And I'm moving more SNMP agents into my network just because of Zenoss.

      i also use nagios, partly cause i never could realy understand snmp. it seems if all i need to do is monitor hardware then snmp is great. but in my case we run in-house code and need to monitor linux and win processes that there are no oids for. i mean can i detect if notepad.exe is runing via snmp ?
    • I've just had a browse, but I can't find an equivalent to the Nagios overview map (the network layout map). Maybe I need to install it to check (not found in screenshots). Without that map it won't work for us..

    • And setup is far less manual.

      This is my top complaint regarding Nagios. It's difficult to configure, and I constantly find myself at odds with the Nagios' configuration strategy. For example, I can't add a host definition without defining some services for that host. This makes sense at some level, but as I install a machine, sometimes I want to add the host definition as a 'placeholder', and define the services later., and the Nagios maintainer

      I also like how Zenoss wraps the monitors and performance graph
      • Good idea on the inventory! I'm suddenly finding myself considering turning on SNMP agents in everything. I have about 1,000 nodes on the network, but SNMP is only running on some core server equipment and switches/routers. I have a number of additional servers that I could spread it to, before distributing to clients. I am curious to see how performance is maintained as I scale up the number of devices. I have Zenoss running right now on a desktop-class machine: 1.7GHz single core w/ 1GB of RAM and 40GB
  • i read about this and thought, "hrm, this is worth checking out." when i went to and clicked download, it asked me to fill out a registration form. submitting the form w/o entering anything causes a popup that indicates email is required. disabled javascript, and was able to submit the form and get to the download page (which, btw is here []). i wonder who the email for confirming my registration will be sent to.....

      You know, they have a big fuck-off "No thanks, please take me straight to the download page >>" link at the top of the downloads page?
  • Look, everyone likes to talk about agentless, and they're full of crap. Everything runs an agent - your agent might be SNMP, or whatever Windows happens to run, but you're running an agent whether you admit it or not. Now the question becomes, why run a crappier agent? Why not run an agent that actually gives you data on your applications []? Everybody knows that your service/server is "working", but how *well* is it working?
