| 19:20.22 | jlp_znc | yeah, something like that |
| 19:21.11 | jlp_znc | but nl appears to understand pages in some way. the man page references header, body, and footer sections of each page (kind of like pr) |

| 21:58.39 | SunSparc | Ever notice how much bandwidth an haproxy health check costs? |
| 21:59.41 | jlp_znc | SunSparc: that's why you set up a dedicated link for those. |
| 22:00.07 | jlp_znc | it does complicate the stonith operations, though. |
| 22:00.08 | SunSparc | I have an haproxy box that is checking 17 servers every second. Watching the bandwidth, that is translating into about 20mb/minute. |
| 22:00.39 | TodPunk | unum: oh, THAT kind of car seat |
| 22:00.54 | SunSparc | jlp_znc: What do you mean by "dedicated link"? |
| 22:01.28 | TodPunk | a specific NIC that only communicates between those hosts |
| 22:01.58 | TodPunk | so if you have multiple hosts you have a switch between them, but it's essentially a private LAN for that purpose |
| 22:02.04 | jlp_znc | what TodPunk said |
| 22:02.20 | jlp_znc | just like having a dedicated network for backups |
| 22:02.35 | jlp_znc | so you keep that traffic off of your main network interface(s) |
| 22:03.02 | jlp_znc | or even run it over a serial link if you only have two machines. that's fun. |

| 22:03.51 | SunSparc | jlp_znc, TodPunk: That would just move the bandwidth though, correct? Not make the requests smaller. |
| 22:04.03 | TodPunk | youtah: dear god people need to learn that their worry is not a cause for anyone else to do anything but mock their immaturity. Fear is not a reason to make policy! Get some data or sit down and shut up! |
| 22:04.14 | TodPunk | SunSparc: yes |
| 22:04.25 | SunSparc | Ok, good to know. |
| 22:04.27 | jlp_znc | SunSparc: True, but then it doesn't impact your main network traffic. |
| 22:04.52 | jlp_znc | (i.e., get in it's way, muck up your bandwidth logs/calculations, etc.) |
| 22:05.03 | SunSparc | jlp_znc: Well, these boxes are all in the cloud or dedicated datacenters. |
| 22:05.17 | jlp_znc | ooooooo, in the "cloud" :-) |
| 22:05.30 | SunSparc | lol |
| 22:05.31 | SunSparc | I am mostly just in awe that status checks alone are eating up so much bandwidth. |
| 22:05.41 | jlp_znc | so yeah, whip up some additioanl virtual nics on them and a new virtual network for the haproxy traffic |
| 22:06.00 | jlp_znc | at least then you can account for it separately |
| 22:06.13 | TodPunk | or just let it be on the main network |
| 22:06.18 | SunSparc | Right. I see what you mean. That could be useful. |
| 22:06.36 | jlp_znc | doesn't haproxy pass around some state, too? (like, iptables state/nat state) |
| 22:06.42 | SunSparc | Is it even possible to make the status checks smaller? Aside from making the checks less frequent. |
| 22:06.44 | jlp_znc | it's been a while since I played with it |
| 22:06.52 | TodPunk | SunSparc: do they need to be? |
| 22:06.59 | SunSparc | Perhaps not. |
| 22:07.23 | SunSparc | But at 10-20kb per check, seems like a pretty big request. |
| 22:07.38 | SunSparc | Maybe that is entirely reasonable though. |
| 22:08.35 | TodPunk | I wouldn't jump to conclusions until you know everything that's in that check. I also wouldn't care unless this becomes a problem. Premature optimization. |
| 22:09.04 | SunSparc | Yeah, I might be overthinking the situation. |
