Sorry to be the negative-nancy, but did Nagios (specifically XI) suddenly become hard or something? Maybe I'm just an old neckbeard by now, but what's with this trend with cloud-hosted middle-man applications (read: expensive web 2.0 frontends) for standard software? If you can't install and configure your own server monitoring, what are you doing hosting your own servers? Am I missing something obvious here?

Though on one hand I'm inclined to agree with you regarding Nagios, on the other hand I disagree. What you're missing is the concept of developer empowerment. I am a sysadmin / operations engineer, and one trend I've noticed over the course of the past ten years is one toward developers venturing further and further into what could be labeled "traditional" systems administration. Do not underestimate developer demand…

I'm not going to get into the pros and cons of "should you hire a sysadmin", but I think the priorities of a lot of these businesses are really screwed up.

Fixed costs like an employee are scary even though services cost more and security isn't even a real concern.

I can't argue with you there. I'm fortunate that my current organization isn't this way, but I have worked at places where this has DEFINITELY been the case. It was mind boggling then and it's mind boggling now. The only explanation I can think of is the (at least perceived) speed and impatience of the modern customer / market. Maybe businesses feel a pressure to make these sacrifices? I'd even go as far as to say the marketing teams for these various "services" capitalize on this feeling of urgency, and try to perpetuate it culturally (e.g. "If you don't use your company is going to fall behind. Here, look at this list of all of the other companies that aren't yours that use our service!"

tl;dr this tool is a cron for your monitoring scripts that reports to a cloud service which then gives you dashboards

Product information that I wish was on one page but instead is spread across five:

  - by default, agent only collects these [linux] stats
    - 1/5/15 min load average
    - cpu usage per cpu
    - memory usage (total,res,virt,cached)
    - network reads per second (RX?)
    - network writes per second (TX?)
    - disk reads per second (only #, so probably iops)
    - disk writes per second (only #, so probably iops)
  - collects output from monitor scripts [that you have to write]
  - sends output to sealion cloud via ssl
  - 'Your password is encrypted' (???)
  - have to edit a couple of files to make it collect info as root
  - have to create your own alerts
  - all data is erased after 3 (free) 15 (paid) or 45 (paid) days
  - features:
    - Dashboard & Charts
    - Alerts
    - Daily Digest
    - Raw output [from your monitor scripts]
    - Quick Setup
    - Enterprise Scale (???)
    - Time Machine (Server data is recorded for a week)
      (this is diff than 3/15/45 days reported above???)
    - Side-By-Side Server Comparison
    - Teams [access controls]
  - Pricing
    - FREE    2 servers  3 days data retention
    - $29/m   5 servers  15 days data retention
    - $49/m   10 servers 15 days data retention 
    - $249/m  50 servers 15 days data retention
    - $499/m  unlimited  45 days data retention
  - agent runs on your servers as unprivileged user
    - made with python 2.6

You mean something like this? http://www.appneta.com/images/graphics/slides/traceview/trac... :) Our languages support is on-par with NewRelic. We just recently release NodeJS instrumentation. Disclaimer: I work for AppNeta. Our TraceView product does what you want and more (across servers, SOA).

Looks nice, but a bit pricey.

Yes, because our offering does more than what NewRelic does.

Well, I doubt it's because that, but because supposedly you have some large clients so you're not so desperate to become a mass-market tool. I personally find New Relic to be extremely expensive as well. The hardware cost of our servers is much less than our New Relic subscription. Also, there are some cheaper than New Relic or similar in cost solutions that do more than what New Relic does (AppDynamics, let's say).
