comment We want capture all login user activity and keystroke
Might also consider moving to containers, so 2k people don't have access to a server, just their walled garden.

comment We want capture all login user activity and keystroke
Capturing keystrokes is a big security no-no, it means passwords will be stored somewhere, and likely not in a secure way. People might use these passwords elsewhere. Log-in and log-out events should be in the `/var/log/secure log. I think a better approach would be to prevent the people from doing the bad things instead of focusing on who. If you require sudo for stuff, then sudo will log those actions.

comment Getting Bonding Status in CentOS 7
But I have active teams, so what is doing the teaming currently? I am wary of loading a module if something else is doing its role?

comment Bosun 0.3.0 / Scollector Consistently Reports Wrong Filesystem Size
@AlexHewson You have it backwards in that last comment, when you put * there is no aggregation taking place. When fields are blank, they are aggregated. If can think of a sensible way to show this in the GUI, create a GH issue suggesting how to indicate that.

comment Bosun 0.3.0 / Scollector Consistently Reports Wrong Filesystem Size
If this isn't the problem, maybe you found a bug. The code that gathers disk stats is at https://github.com/bosun-monitor/bosun/blob/master/cmd/scollector/collectors/di‌​sk_linux.go, It gathers these stats from the df command: "df", "-lP", "--block-size", "1"

comment Troubleshooting a Redis Stall
We have it set in puppet, but as an exec. I don't see it in rc.local, so my current hypothesis is a race condition - redis starts before the kernel switch is set

Mind enlightening us to what is going on during a thp split?

comment Troubleshooting a Redis Stall
There is a thp_split that is a close correlation. Some lag in recording but the monitoring agent timing could have been impacted as well. Updated the question with the graph!

@GregL You're second link is to the same SF blog post, so a miss paste there you may want to update.

comment Bosun - Logstash Connectivity
@DilruwanMadubashitha: Not currently. The items and graph page are opentsdb specific (including metric completion). The graph page is OpenTSDB specific in it's design. (You can however view graphs of lscount() and lsstat() results on the expression page. For the items page, I don't really know what you would expect to see on the items page due to the nature of free form documents (what ES stores). What would you picture it showing exactly?

comment Routing selection: specificity vs metric
@jch Does quagga and co. mimic AD by setting the metric accordingly? (Not that your point isn't vital, just curious)

@growse: No idea - if I could answer that I wouldn't be asking random people on the internet how to manage my HBase cluster ;-)
