Bryan Boreham b117b1a5ef cosmetic: move misplaced import 2020-05-19 10:09:52 +00:00
Bryan Boreham ad82fafde8 multitenant: scan container command-lines as well as process 2020-05-19 10:09:28 +00:00
Bryan Boreham f83ad517d8 multitenant: extract command-line parsing function and add test 2020-05-19 10:07:23 +00:00
Bryan Boreham 323aa46d1c fix (pipes): check websocket errors inside CopyToWebsocket() 
Previously we were treating EOF on the reader as no-error, meaning
that operations like Kubernetes Describe would retry endlessly when
finished.

Bryan Boreham fa4d1c4c2b Upgrade reports before merging 
In case they came from an older or an overload probe.

Bryan Boreham b772fa83b3 Add a metric for topologies dropped because they are over limit 
Need to modify DropTopologiesOver() to report what it dropped, and
plumb through the userid so the metric can show who has a problem.

Bryan Boreham 9a739fda46 Parallelise sending merged reports to store 
Writes to DynamoDB and S3 can be done in parallel, which will reduce
the overall flush time.

Bryan Boreham ccf031b8a9 enhancement(multitenant): merge incoming reports in a time window 
This means we store fewer, bigger, reports, which reduces cost of
storage and time to render when data is viewed.

Bryan Boreham 104b9cba50 refactor: Call Close() on collector 
Doesn't do anything at present, but will be used later.

Change the signature on BillingEmitter.Close() to match. Note we didn't use the error returned.

Bryan Boreham 777ff07e19 refactor(multitenant): break report storage code out into sub-functions 
So the main Add() function isn't so long.

Bryan Boreham 8c46367808 fix(multitenant): move use of rounding map inside lock 2020-04-13 16:16:20 +00:00
Bryan Boreham 3f11352435 enhancement(multitenant): Track rounding error in billing calculation 
Billing takes an integer number of seconds, so keep track of the
amount lost to rounding when the publish interval is not an integer.

Bryan Boreham c784acc20d Revert change to use report timestamp 
This reverts commit 6b72246fe6.

The app merges reports within a 15-second window of its own time, so
if one or more probes have a time that is several seconds different
they will get excluded from the window.
 2020-03-28 13:58:34 +00:00
Bryan Boreham 6b72246fe6 fix (multitenant collector): Use consistent report timestamp 
Previously the code called `time.Now()` in two different places so the
timestamps didn't match. Now we use the timestamp of the report itself.

Add the collector's local time to the report if it didn't have one.

Bryan Boreham 53701aca1f Cache the last-known report interval per user 
Delta reports don't contain the string we are looking for, so remember
it from the last full report.

Bryan Boreham a47cf0a2aa Remove copying Merge() on Report 
It was only used in a few places, and all of those were better off
using the Unsafe variant.
 2020-03-06 15:03:43 +00:00
Bryan Boreham 329023b7c5 Improve calculation of usage in multitenant code 
Use the duration supplied, if there is one.

It was looking for a process named "scope-probe", whereas the
executable is just named "scope".

Bryan Boreham d516ed9883 performance(aws_collector): don't persist shortcut reports 
Shortcut reports are sent to update the UI quickly, on events like a
container starting. We don't need to persist them in the time-travel
data since the same information will be covered by a regular report a
few seconds later.

Bryan Boreham 74b6a292d5 Use time.Duration instead of nanoseconds for constants 2019-09-13 07:31:07 +00:00
Bryan Boreham b5376facf2 Cache merged groups of reports, to reduce the number we handle in parallel 
Previously we would merge all reports in a 15-second window.
Now we use a 'quantum' of 3 seconds, similar to the single-user app.

E.g. a 30-node cluster will have 150 individual reports over 15
seconds, but the new code will merge 5 pre-merged reports plus 20-ish
very recent individual ones.

This limits the max heap size used for deserialising, since we only do
3 seconds at once per instance.

Individual reports are still put into the cache, but should get
displaced by the pre-merged ones under LRU.

Bryan Boreham 4c74f8b1cf Add metrics for report size and count per tenant 
In a multitenant system it is useful to be able to drill into which
tenants have the most or biggest reports.
