Low Cost and Free Monitoring

by Jonah Kowall  |  October 3, 2012  |  11 Comments

With some of the research I completed towards the end of last year, I take a pretty consistent set of requests on the evaluation and use of open source monitoring. If you are following some of the fun conversations on “monitoring sucks” you will notice that not only do most traditional monitoring systems fail to deliver any high value in general, but they often fail and do poorly. The reaction that many have had is trying to implement open source to reduce the cost, since it pretty much “sucks” anyway… logic makes sense, but the issue is that Nagios and other related open source tools are often much worse than commercial solutions. Another approach to getting ahead of this problem is looking at monitoring which comes with the purchased technology stack (Microsoft, Oracle, VMware, SAP, and others). An alternate way is to investigate the many lower cost and free monitoring tools on the market. These companies often sell significantly less expensive tools which have 80% of the functionality for much lower costs. They often have freeware versions or limited versions. I have put together some discussion on this point along with some insight into many of the solutions on the market.

Solutions covered in this research covers traditionally deployed solutions including : Ipswitch, ManageEngine, Solarwinds, Correlsense, Groundwork, Jinspired, Net Optics, OP5, Paessler, Spiceworks, Splunk, VMTurbo, VMware, Zabbix, and VMTurbo

We also cover those free and low cost tools deployed via monitoring as a service (SaaS) including AppFirst, Boundary, Datadog, GFI Monitis, New Relic, ScaleXtreme.

    Interesting that you talk about the open source version of Nagios in your article then not include their commercial version on your research? Seems like incomplete research to me. Nagios XI is by far better than all of the products you listed.

  • 4 Jonah Kowall   December 13, 2012 at 2:03 pm

    Gartner clients don’t typically short list Nagios XI due to the fact that it’s missing key features within the dashboards, scalability, and a lack of topology relationships without manually configuring them. This is the reason that clients move towards OP5, Opsview, Groundwork, Centreon, and a couple others versus XI. What features makes you believe that XI is a better product than others?

    The management team at Nagios doesn’t really speak with analysts or really do any effective marketing, It’s of no cost for a vendor to brief analysts, and all of them should do so. Normally I request briefings when clients ask about products, but I haven’t had a client ask about XI yet!

    I believe in this article and other articles you attack nagios like without compassion but for technical audience you give NO reason to put that tool 3 steps below to any other. You can be in trouble killing companies reputation without reason as a matter of fact I don’t understand how Gartner dont control this type of “reputational-killing” opinions must be backed up by factual reason.
    Anyway, I found your opinions quite interesting although I found you mistaken once in a while.

    Nagios is not a company, its an open source tool. In fact the vendor mentioned above… OP5 contributed over 90% of the Nagios 4.0 codebase, which you get for free!

    Factually, I’ve spoken to hundreds of Nagios users who have good and bad things to say about it. I think the tool is great if you have the right talent level and have done configuration management and standardization (Chef, Puppet, etc). This is normally not possible in today’s mixed IT environments, but startups and web companies can do it and should do it.

    Setup a briefing. Please review and fill out the form on the following page :

    · Send a powerpoint deck and a link to the web conferencing of choice
    · Use webex, citrix, or (free)
    · Use the Gartner bridge for audio

    General : Background on the company, employees, locations, revenue, customers, average sale price, and a simple value prop.
    Articulate value!
    The slides and discussion does not need to be only technical, but a demo and technology is important.

    I have started using for monitoring my web servers. They are providing cloud host, local host and hardware host monitoring solutions all at one platform. I signed up for free and got 50 tests absolutely free.
