Network and Server Monitoring

I recently purchased a new siem, I just realized that it don't do any sort of network monitoring, for instance I have a product that will ping a server or router, etc every 5 minutes and email me if it goes down and it will also monitor cpu, storage and memory on servers.  Does anyone know of any freeware products that will accomplish this?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There's quite a few of these monitoring tools out there, it's just what you feel comfortable using, can it be Open Source and using Linux or does it need to be something running on Windows only?

What do you want to monitor, the things you mention are already monitored you say, or are these you want to monitor?

Thanks for clarifying.

I'll give some freeware/Open-Source monitoring tools to start with:

PRTG has some good functionality. It is free for up to a certain number of monitors. The paid version up to 100 monitors is only like $500 I think.

I'm looking for something that can tell me if something that is pingable is down.  Also something that will alert if say a processor is spiked for more than a few minutes or memory is pegged etc.

PRTG does this. So does Spiceworks I believe.

I have never tried PRTG, I'll have to take a look, Spiceworks is pretty terrible

PRTG is not bad especially if you are talking on the no of sensor type to be supported. Other include
a) Zenoss Core - It has event triggers and notifications (e.g. create notifications to send email or pages, create SNMP traps, or execute arbitrary commands in response to an event), also see the "Notify Me of Important Events" that can be rule-driven

b) Nagios - commonly known for its Nagois Core (vs Nagois XI - commercial) but free version can be manual and effort required . However the scripting provided will proved flexibility and can customise as required

c) Zabbix - as in all other, it also drill (if needed) into provides IPMI access for h/w monitoring, and can run IPMI commands to turn on or off devices over the network. Likewise, it supports SNMP agents, present in all network devices like routers and switches. OVerall,it can also augment to send notification messages via e-mail, SMS or Jabber (XMPP protocol) for each notable event. Typical workflow in broad is like sending notifications, allowing acknowledgement of information received, escalation of information to other people, and ability to take actions.

NetCrunch 8 is a solid option if you're looking for an all-in-one solution. It's agentless, has an embedded SQL database, and will monitor most of your devices out of the box with the included monitoring packs and MIB database. If something is not already stored, there's also a built-in MIB compiler. It's not free, but it's a price leader and should pay for itself quickly in time saved. Otherwise, Nagios is the go-to free option, it'll just take you a bit of time to configure,
