Monitoring (both inside/outside) - What Do You Use?

I asked about this some time ago, but the landscape changes so fast.
What do you use for monitoring, where monitoring is both:
- from the outside - such as ping, checking http, etc. There are a million products and external services (I like NodePing) that do this.
- from the inside - getting status from the box from inside, like "did MySQL go down" or "was there a RAID event"

What I do internally at least:
I use something cPanel made a while ago, you can find it below.
https://github.com/cPanelTechs/SysSnap
You don't need cPanel for that btw. I combine this with a tcpdump cron every minute for 5s, cleared by daily cron. So if I know something happened around X time, I'll pull the logs from cPanel's script which shows what was running and all that jazz, then for real in depth answers on the network activity I can pull the tcpdump cron by it's timestamp. Absolutely nothing gets past you like this.
Monitis for ping monitoring from multiple locations; UptimeRobot as a secondary monitor.
Munin and htop, etc.
NodePing, and Observium
using NodePing and Observium
I thought Observium was more of a Cacti-like MRTG-like graphing/capture/SNMP analysis tool.
Does it do things like MySQL is down, scraping /var/log/messages, etc.?
Nagios cuz I'm used to it.
Internally: webmin system status or Longview
Externally: uptime robot & status cake. Application layer (HTTP w/ keywords)
Used to use Zabbix in and out. But switching over to NewRelic and Splunkstorm just because its easier to add nodes.
I use pingdom and a central cacti server to monitor all my http and asterisk VPS. I also use Monit on each of my servers that is configured to send me an email alert via Amazon SES whenever a monitored service or iptables goes down. It works great.
I also use AIDE to monitor for unauthorized filesystem changes. It helped me a lot during a previous security breach at one of my VPS providers - using AIDE I was able to be sure that none of my system files was modified by the hacker.
NewRelic and StatusCake
For all my customers (dayjob) I use PRTG both internally and external.
Good to see someone else who likes a bit of SysSnap
top, free -m, netstat -antlp
A bit offtopic, but what happened to OpenStatus @NickM?
I stopped having time to work on it, basically. It does, however, live on in HostGuard's monitoring system
Maybe at some point, I'll consider putting out a new standalone version.
Pingdom for external host up/down monitoring and Icinga for internal more detailed monitoring like RAID status, load etc. Icinga gets configured automagially by Puppet. Then of course Observium for graphs.

New Relic, Pingdom, StatusCake.
