No panacea in max repetitions (But difficult to really tell what with the CMTS's changing)


Gather Bryan's been reconfiguring the demo instance to run against the larger CMTS (now scanning 2500 modems), so I don't know if there was any change in processing load between the limited and unlimited queries. Going to leave the changes in-place because it seems very likely that they will have a positive effect ...

Cleanliness is next to leak-less-ness (Or rather much-slower-leakish-ness...)


Well, the memory leak (whatever it is) is down to about 50MB/day. That's still not going to work in a production environment, but it's slow enough that the demo can run for about 11 days (well, make it 10, it needs some ram available for actually interacting with users). It's also ...

New TwistedSNMP available (Allowing you to pass maxRepetitions into your Get Bulk requests)


I haven't had a chance to test this theory yet, but it makes so much sense...

When doing get bulk requests (which are done once for each modem on all non-intensive scans in Cinemon), the default behaviour for an agent is to encode 255 records for each requested field. That is, if you are ...

Ruminations on going back to Windows for a day


Been working in Windows all day (good old reliable Windows ;) ). I'd forgotten how much more worn-in my working environment is here, everything set up for two-key access, everything defaulting to opening in the right directory, every tool winnowed from the pack over years of Darwinian selection, every device "just working", without few if any ...

A day passes, only one official 'item' crossed out, and it's not a key one (Spent most of the day in auditing and cleanup trying to find memory leak...)


Did rather a lot of cleanup of the code today. Finished a number of "polish" elements (e.g. links upward in the hierarchy, retaining hierarchy names and comments through upload/download cycles, that kind of thing). Confirmed that email alerts do work when the email account is set up.

Last task of the day was ...
