| mithro | Do you get zero underflows in the case where it does work? | 05:37 |
| mithro | _florent_: Enabling the I2C stuff seems to cause the firmware to lockup, I'm currently trying to debug | 05:43 |
| mithro | _florent_: Is that feature ready to be cherry-picked across? | 05:43 |
| _florent_ | mithro: yes underflow is zero when working | 05:43 |

| *** CarlFK has quit IRC | 13:32 | |
| xfxf | jea: micolous arrives sometime today (Thu), so you'll need to switch gears into streaming stuff later on tomorrow i'd imagine | 13:41 |
| xfxf | i guess this is somewhat contingent on the state of the machine imaging, though | 13:42 |
| xfxf | but perhaps a good time to do it given the streaming scripts should be baked into the ansible stuff | 13:42 |
| jea | I'm hoping to move to monitoring and streaming tomorrow | 13:42 |
| jea | yes, I hadn't thought about the streaming being in ansible, but that makes sense | 13:42 |
| xfxf | rad. deeprave has been hacking on hdmi2usbd, should hopefully have some last bugs ironed, which will make the monitoring easier | 13:43 |
| jea | ok, that sounds good. then it will just be sorting out the data we want to capture, and pushing it somewhere | 13:44 |
| xfxf | at an absolute minimum even logging locally + using logrotate every hour or whatever would be good | 13:45 |
| xfxf | a nice feature might be to have it connect to vocto + split log files when a cut happens | 13:45 |
| xfxf | it'll make matching a log file to a video file super easy then | 13:45 |
| xfxf | i'm happy handling the logging/sending stuff somewhere side of things if you want to investigate the monitoring | 13:46 |
| *** hyadez has quit IRC | 13:46 | |
| xfxf | and the data normalisation | 13:46 |
| xfxf | logstash seems interesting | 13:46 |
| jea | splitting log files, or at least logging a cut somewhere in the overall system would be useful | 13:47 |
| xfxf | i can see for mithro having a set of log files that directly correspond with our recording files being excellent for debugging | 13:47 |
| jea | logstash sounds good, but i haven't looked at it enough to say what it is like. i guess i'll find out soon! | 13:47 |
| xfxf | you'll be able to see in the video when people are futzing around + match that easily to the right log file | 13:47 |
| xfxf | indeed | 13:47 |
| jea | yes, i think that would be easiest for mithro | 13:47 |
| jea | i'm going to write a generic data gathering tool, and allow it to output to multiple things (file, time series, etc) | 13:48 |
| jea | that way we can easily push the data to where we want | 13:48 |
| xfxf | rad | 13:48 |
| xfxf | down the track i can see a ton of useful metrics we'd want in AV HQ for future events beyond the opsis monitoring | 13:49 |
| jea | definitely | 13:49 |
| xfxf | plus the way the recording machines are being built is everything is systemd | 13:49 |
| xfxf | so i'd imagine we can do a bunch of stuff there too in terms of monitoring events | 13:49 |
| jea | i'll model it on what eventstreamer used to do, but make it more extensible | 13:49 |
| jea | (and no perl...) | 13:49 |
| xfxf | heh | 13:49 |
| xfxf | my biggest concern with eventstreamr too was it became _the_ way things were started/invoked | 13:50 |
| jea | yes, i expect systemd to help a lot with that actually | 13:50 |
| xfxf | i'd really want the monitoring decoupled | 13:50 |
| xfxf | not that it shouldn't be able to restart services, but in a decoupled way | 13:50 |
| jea | i want eventstreamer 2.0 to be lots of individual components that can be deployed in any way - monitoring, service management, etc | 13:50 |
| jea | and there should actually be a streaming component to it for once | 13:51 |
| jea | instead of a mostly empty folder | 13:51 |
| * jea sleep | 13:54 | |
