It is not a secret that SNMP is a little bit of a mess when we need to know whether a device is compatible with a particular OID. The only way to be sure about it is by testing the OID against the device, and the result of this test will depend on several variables such as device model, firmware version, firmware package (IP Base, IP Services…) , features enabled (EIGRP, HSRP …) or even how the features are configured (BGP in basic mode or AF mode).
A common complaint that I receive when I’m onsite delivering consultancy or training on SolarWinds is that alerts can be disconnected from what you see for the device status on the web interface. I understand that this is quite annoying when you check a device and you see its status is green when the same device has a critical alert.
Do you know that expression we say a lot in IT? “first get the basics right”. Actually, it is a big truth, we, as IT engineers, love to use cutting-edge technologies, configure complicated stuff, spend lots of hours trying to figure out how to use that advance feature that guy at the IPEXPO told us was possible.
Do you guys remember the movie Minority Report? In this movie, there are three psychics called precogs that are part of “Precrime”, a specialised police department that could apprehend criminals based on foreknowledge provided by the precogs. I have to admit that I like the movie because it makes me think whether this is something that would be accepted in our society in the present day. But also makes me wonder if we could do something similar with our network devices, and catch the bad guy before something nasty happens on your network. In this case, we don’t want to put anyone in jail, we just want to be sure that we have the tools to identify, take action and revert any changes.
Last week my good friend Dan asked me if he could get a report in SolarWinds that displays the last time the Windows servers were patched, and, if possible, which the patches were deployed at that time. Now I must point out that Dan does not have the SolarWinds Patch Manager solution, which provides this information natively, oh and the ability to perform all system patching tasks, but Dan does not have Patch Manager. Still, the answer was ‘sure it does, it’s SolarWinds!’
