bb3bfd4 fix condition for close probability (#1524) Swaps the body for the condition so it matches expectations. Before it was doing the opposite, so setting to 0.1 would close ~90% of connections rather than ~10%. 27 February 2023, 22:28:36 UTC
36a0416 akka: add helper trait for http client (#1522) Can be useful for unit tests with a more descriptive type than just using a function type. Co-authored-by: brharrington <brharrington@gmail.com> 25 February 2023, 01:09:16 UTC
b9a0837 add helper for monitored thread pools (#1520) Adds a helper class for creating an ExecutionContext based on a java thread pool. This includes using a factory with named threads and setting up the spectator monitoring. 22 February 2023, 15:10:35 UTC
86b6d6f use CORS origin as id (#1519) For requests coming from UIs that have an allowed origin host, use the origin as the default id. If one is explicitly specified via the uri parameter, then that will still be used. 15 February 2023, 17:26:00 UTC
14008a9 support default name when creating id (#1517) For some use-cases the tag maps may not have the `name` that is required by Spectator. If that is desirable, then a default name can be used to still be able to leverage utilities like the query index. 08 February 2023, 19:03:38 UTC
bc2c9b8 adjust log settings for akka (#1518) Helps to avoid timeout during logging initialization. 08 February 2023, 17:01:25 UTC
ad4e200 add Id view for SortedTagMap (#1516) Adds a `toSpectatorId` method to provide an efficient view of the SortedTagMap as a Spectator Id. This can be useful when using the Spectator QueryIndex to avoid conversions. 31 January 2023, 20:46:44 UTC
f08447c use context.id for blockingQueue metrics (#1515) Ensure the id is passed through to the queue metrics when using ClusterOps.groupBy. Also updates it to use preMaterialize rather than a publisher. Co-authored-by: Yingwu Zhao <yzhao@netflix.com> 18 January 2023, 21:52:10 UTC

b990089 grapher: use id parameter if present (#1513) Before it would always set it to `default` when processing the URI and the caller would have to set it to another value later. To get better consistency, recognize the id parameter when present. The caller can still override with additional logic if desirable. 16 January 2023, 20:33:32 UTC
dd859d8 add graph config to data request (#1512) This is sometimes useful to provide more context to the data layer such as passing through the query id. 14 January 2023, 00:41:00 UTC
810f36a make tests pass when running on M1 Mac (#1510) There are some differences in image rendering and floating point on the ARM M1 processors that cause tests to fail. This will need some more work, but for now disable those tests when running on ARM. The CI will still catch any issues before merging. 13 January 2023, 16:09:11 UTC
1dd6ea2 update Palette to allow all colors to be accessed (#1509) Convert the Palette to require an ArraySeq of colors. Rename the parameter and implement colors() to avoid code changing in other places. This allows the full set of colors to be accessed directly for use with things like heatmaps. 13 January 2023, 12:39:03 UTC

c2dd5c3 remove redundant clauses when normalizing (#1505) In some cases with tooling a `:cq` can get applied multiple times. If the common query condition has an OR clause, then that will get expanded with the cross product when computing the DNF. As a result, the normalized query resulting from applying a `:cq` once would differ from applying the same `:cq` multiple times. This change removes redundant clauses from the normalized OR set to avoid the discrepancy. Redundant means that the removed clause will not change the result since another branch of the OR would have matched. 14 December 2022, 23:59:05 UTC
8e7368c dedup or clauses when normalizing (#1504) Update the expression normalization to dedup OR clauses if the conditions are the same. 14 December 2022, 18:34:08 UTC
9a59fca use stat placeholders for normalize (#1503) When normalizing an expression that uses a filter, use one of the `:stat-$(aggr)` placeholders if possible. This avoids duplication of the input expression making them easier to read. It also helps if comparing expressions after normalization to see if they are equivalent. 14 December 2022, 13:09:40 UTC
3fe64d9 dedup query clauses during normalization (#1502) Update the normalization logic to deduplicate the same query clause within an conjunction. Also deduplicates terms within an IN clause and maps to an equals check if there is a single term. 14 December 2022, 01:24:48 UTC

8bcf47a add support for duration tick labels (#1497) Adding support for `&tick_labels=duration` that will scale ticks from picoseconds to years. Also change the legend behavior so that counts are no longer tagged with the same prefix as the other stats to differentiate in binary and duration mode. Fixes #1047 01 December 2022, 13:47:07 UTC
2f7054a add value function to dedup inputs (#1500) When pushing data to memory the blocks can easily overwrite when an update for a given datapoint is received. In other use-cases this can be quite expensive and undesirable. This change adds a value function that can be used to buffer the updates for a window of time and dedup the data. 29 November 2022, 12:27:33 UTC
30b4a5b add option to disable CORS (#1499) If we are proxying to another server that already supports CORS, then having multiple layers adding the CORS headers can cause problems. 23 November 2022, 21:15:48 UTC
25d2005 jackson 2.14.1 (#1498) Pull in some memory and performance optimizations in jackson ([2.14.1]). [2.14.1]: https://github.com/FasterXML/jackson/wiki/Jackson-Release-2.14.1 22 November 2022, 17:09:08 UTC
ae06f6b flush meters when a time grouping is emitted (#1496) When TimeGrouped flushes a finalized time grouping also have it explicitly flush the batch meter updaters. This avoids the counts potentially showing up much later due to a low rate. 21 November 2022, 19:48:43 UTC
34ed816 ignore heartbeat for dropped old (#1495) The heartbeat just ensures the stream keeps moving even if there is no data. It is expected to be delayed from the actual flow a bit. 21 November 2022, 15:02:23 UTC
73e7ec8 parse messages after merge of streams (#1494) Moves the step for parsing messages after the merge of streams from each of the LWCAPI nodes. This makes it easier to keep track of the overall number of concurrent requests and ensure it backpressures rather than enqueues. Also changes to use the ordered variant. Preserving the order could be important to avoid newer messages getting pushed through first and moving the cutoff point for the time grouping. 21 November 2022, 13:17:47 UTC
bf3d844 monitor flow just after evaluation (#1493) Add a check to monitor the flow just after the final evaluation step and before flattening the messages. This helps show the overall delay for a downstream consumer which is more relevant than the delay for the indvidual messages. 19 November 2022, 15:29:20 UTC
5e60008 add hint for controlling y-axis color (#1492) Adds a rendering hint, `ambiguous-multi-y`, for the graph image that will disable the behavior of using the first line on an axis for the axis color. Instead it will use the color selected based on the theme. As indicated by the name, in this mode there will not be any visual cue as to which axis corresponds to data on the graph image. 18 November 2022, 04:10:49 UTC
82b412f lwcapi: only update subscription list on changes (#1491) Creating the full list of of all subscriptions can be expensive when there are a lot of expressions. Update it to only be done when there are changes the same as the query index update. 14 November 2022, 16:58:34 UTC
e8b9b49 lwc: keep input to TimeGrouped batched (#1490) Refactors the stream from parsing the messages from lwcapi to the TimeGrouped stage to keep the datapoints batched. This significantly reduces the number of messages passed between the stream stages and achieve a higher throughput. Also creates a dedicated thread pool to use for parsing the messages as that is the most time consuming step. 13 November 2022, 15:28:35 UTC
358aef3 lwc: remove some monitorFlow steps (#1489) When processing data with a high input volume the `ConnectionSources`, `InputLines`, and `LwcDatapoints` monitors would have a high throughput and the same number of elements flowing through. This change removes two of them so there is now just `InputLines`. This helps reduce overhead in the hot path. 12 November 2022, 20:37:44 UTC
d68272f lwc: use SortedTagMap for data points (#1488) The main advantage is that for eval it can just quickly copy into an array without all the hashing and extra space in the hash array to avoid collisions. Note, this change is safe to roll out as long as the lwcapi service is pushed first. 12 November 2022, 00:32:23 UTC
23bc96d switch to spectator batch updaters (#1487) Use the spectator batch updaters in some of the key parts of the eval stream that were manually batched before. 11 November 2022, 20:04:19 UTC
55485bd batch meter updates for TimeGrouped (#1486) Batch the counter updates in time grouped to avoid updating them in a tight loop for high throughput streams. 10 November 2022, 19:37:28 UTC
2374aff batch updates to meters when monitoring flows (#1485) Updates the monitor flow stage to batch the updates to the meters. This avoids some of the overhead for calling gettimeofday frequently for high volume streams. 10 November 2022, 19:33:22 UTC
3e935c1 only update index for new items (#1484) The updates for the existing items will get filtered out later, but we can avoid adding them in the first place to reduce the overhead a little bit. 10 November 2022, 02:15:48 UTC
70565a0 remove usage of javax annotations (#1482) These have been moved to jakarta in later versions. With the way we are using Spring, the annotations are not necessary. 10 November 2022, 00:12:58 UTC

6b11ea0 improve performance of batch index update (#1479) A lot of the time and allocations were being spent sorting the items passed to the index. Java uses TimSort internally when sorting object arrays and that uses a merge sort. It allocates a bunch of temporary arrays when performing the merges. This change leverages the fact that the items that are already indexed will be sorted, so we can just sort the new items and merge the two sorted sets. 08 November 2022, 19:19:48 UTC
397cdcf add expression to v2.json output (#1480) Update the `v2.json` format to include the query expression for the lines. This makes it more consistent with the time series messages used with fetch and LWC. 08 November 2022, 19:15:09 UTC
71098c9 json: fix double parsing for large integers (#1478) Before when using `JsonParserHelper.nextDouble` if the raw encoded value looked like an integer type it would try to access it as a long, then convert the long to a double. This causes problems for larger integers that cannot fit within the bounds of a Java long. Now it will access it as a double. 07 November 2022, 22:06:11 UTC
3143e37 use custom JSON encoding if specified (#1477) If a class extended JsonSupport and provided a custom encoding it would get used by the interited methods, but would get ignored when using `Json.encode`. This could create problems when an object is nested because the custom encode would not get used. The `Json.encode` could not directly call encode, because it would create a loop with the default implementation. This change adds a method that can indicate if it is desirable for `Json.ecnode` to use the custom encoding. 28 October 2022, 22:44:34 UTC
6096696 allow image to be disabled for v2.json (#1476) The image rendering can be computationally expensive and increase the size of the payload quite a bit. For some cases it is desirable to use the `v2.json` format since it is similar to fetch and LWC, but the image is not needed. Alert processing is one example. This change adds a `hints` URI parameter that can be used to pass arbitrary hints back to the rendering engine that is used. The `v2.json` engine has been updated to omit the image if a `no-image` hint is passed. In the future we may want to only include the image if requested, but that would be backwards incompatible and break some current usage. 27 October 2022, 20:22:11 UTC
3205dfb improve legend for custom avg with nested grouping (#1475) Updates the simple legends generation to handle the case of custom averages used with nested grouping. Before the logic to remove the named rewrite would also remove the first grouping and break the rewrite of any later groupings. 27 October 2022, 17:20:17 UTC
b9f4d8c update normalize behavior for UI (#1474) Updates the behavior of normalize to reflect preferences of the UI team. In particular: - It will not try to extract common query aspects into a `:cq` clause. - The helpers for filtering based on summary stats will be preserved rather than expanding. - Adjust handling of OR clauses in a query. First convert to DNF and then sort the CNF clauses to avoid awkward expansion with repeated terms. 25 October 2022, 21:45:16 UTC

42c1f2f adjust consolidation behavior for rates (#1467) Port an old internal fix to ensure we have consistent behavior.
