I feel like Quest's PacketTrap really flies under the radar. Its a top of the line network monitoring tool i dont hear many people talking about. Need to host yourself but still great, and support is very helpful Another new one is MXAlerts. They only offer email server motoring (using round trip monitors) but the price and simplicity are great!
I'm kind of surprised Hyperic isn't mentioned on this list. http://www.springsource.com/products/systems-management
ntop is one of the most valuable tools in my network monitoring kit. Can't beat the price (FREE) if you run it on a *nix platform or compile your own Windows executable. A pre-compiled Win32 version is available for less than $100USD and includes one year of free upgardes and support. http://www.ntop.org/overview.html
Network monitoring tools should be able to bring information about availability, traffic, services status (in the case of servers) and a visibility of the network topology i think. In my opinion Zenoss is the best open source tool.
A true comprehensive list of network monitoring tools can be found at http://www.slac.stanford.edu/xorg/nmtf/nmtf-tools.html
For large Enterprise Network monitoring we use Statseeker. Relatively simple to setup, Capable of polling using SNMP and receiving input from SNMP-Traps & Syslog, it also stores data for an extended period of time allowing trending over a long period of time (i.e. years), and is very scalable (We are monitoring over 5000 devices and over 45000 network ports.). It also does event, and threshold alerting, and you can also custom script your own requirements. Having said that it is mostly network centric, i.e. it primarily monitors routers and switches, The latest versions have incorporated Server, UPS, Printer monitoring, but these aspects are not as well developed as the network side is (The other monitoring systems are catching up pretty quickly.)
mrtg is very powerful - set it up many years ago and once I got it going it was a dream to behold - however as I recal it is what you might euphemistically call "non-trivial" to get it running! The graphs look just like thos of munin and Zenoss, probably all three based on / grew from the same original Linux code I guess. IT service view is a lot less of a mission to configure, all done in one GUI, but also takes some getting used to. Once it's set up & running you can also forget about it though - it just works.
We use it for automatic logical network maps and views of physical segments with port numbers, agentless monitoring of Windows, Linux, Mac OS X and full support of SNMP. Looks like it is more popular in Europe and Asia, or am I wrong?
How complete is this is you missed The Dude and OpManager Manage Engine? The Dude is free and fairly powerful while OpManager is VERY powerful, configurable and cost effective to manage larger networks.
Please correct me but I only see 12 listed. Perhaps number 13 is too hush hush for the likes of me. :)
I am really suprised WhatsUp was not listed here. This is easier to configure and has better dashboards than all of these
Is t a free tool? If not, how much do you pay for a licence (for example 1000 nodes). Do you pay for year support? Thanks
OpenNMS is open source and way better than WhatsUP Gold... They also have a great community that support the software even though it's open source
The nightly scan and 4 hr "health" scans gives you a lot of info. It's not really a monitor. You can make a device offline alert but not much else. Use one of listed tools and set it to email spiceworks.
We use Solarwinds for most things but for non chart based service based notificatons you can't really beat Big Brother from Quest Software The free version is excellent We also use MRTG, Cacti and Nagios
I'm not sure how I came up with an extra. Thanks for pointing it out, though. The title is changed accordingly.
Among all the others i think The Dude (from Mikrotik) must also be listed. I have it in some clients and it is just great! Besides it is completely free.
Advanced Host Monitor for windows, linux and network systems. UNNOC, no longer being developed but presents an excellent graphing and correlation engine for VI3 instances.
I'm also missing Zabbix. Excellent tool IMHO. Especially when you need historical performance/statistical data with full detail, not compressed into rrd graphs. It also does service monitoring, web monitoring etc and adding custom checks can be done really easy.
Yes It does cost, but for obvious reasons I cannot disclose how much we pay. (plus I cant remember anyhow.) we have been using it for so long that I dont even remember if there was a upfront cost, However we do continue to pay a yearly maintenance fee. There is a Free trial licence avalible on the Statseeker website, If you are interested I recommend finding their website and trying it out.
None of the programs listed are "Real Time." When it comes to network monitoring at least in my experience there is really only Near Realtime. I know typically within about a 10 or 15 minute window if one of my critical servers, devices or services is down and get an alert from Spiceworks. You just have to setup Spiceworks to do a Network Health Scan and viola it works like a champ.
Expensive. Used it, liked it, didn't want to pay for it. Lots of other stuff does as well - for free.
It's obvios that you get a good performance because of the server you have. But it sounds like a good tool. It'll be on my list, i wanna try it. Thanks.
the Statseeker guys could answer better, but I think (based on the info published on their webpage in the tech support help section) it sounds like your server should be able to deal with the load. From memory we are running a Dual Quad core server with around 16G of Ram and 6 x 80G HDD's in a raid 5 config, It is complete overkill and the server Runs at less than 20% util :-) but by the same token we dont have any problems when multiple users are all on there generating reports simueltaneously. -=-=-=-=-=-=-=-=-=-=- from Statseeker Tech support Page For best performance we recommend the following: Up to 20,000 network interfaces and minimal NetFlow collection requirements: * 64 bit Dual Core CPU, with 2MB of L2 cache for each core * 2GB RAM * 500GB Hard Drive * Gigabit capable NIC
I really find it interesting. Specially for the number of nodes that you are managing. I'm going to try the trail version. Is there any hardware requeriments in order to manage more than 500 nodes? I have a 4GB RAM, 512 GB hard disc, dual core server. Would it be enough to manage 1000 nodes?
The title of the article speaks for itself "13 of the most recommended network monitoring tools". HPov is clearly not one of those that falls into the top 13! HPov is complex, expensive and difficult to manage & maintain. My personal fav. is Solarwinds with a number of their plugin's NTA, NCM etc etc. Good balance of being cost effective, being able to provide a good support model and a large 'thwack' community following :)
Hello! Anyone ever hear of it? It is interesting that this article didn't list products from any of the top 10 network management and monitoring vendors.
Im currently in school and am interested in knowing about these free tool and where did you find them. please to reply to firstname.lastname@example.org. Thank you
Sorry but i try WhatsUp half a year ago. I was interested in managing alerts for threshold of traffic and it didn't meet my expectations because i had to configure one by one the alerts with special commands in the router or switch. I did not try its other benefits. I'm working with Zenoss Enterprise .... for now it has all i need.
