| 2b0996e | brharrington | 13 June 2019, 17:38:02 UTC | fix build settings for 2.13 to use `-release 8` (#1055) Before it was looking specifically for version 12.

Now it performs the same check which avoids errors like: ``` must have 1 or more time series to perform aggregation ``` | 30 April 2019, 23:41:51 UTC |
| 049a878 | brharrington | 30 April 2019, 16:54:42 UTC | fix eval state for sparse lines with group by (#1035) Before, if a line was sparse, for example an error counter that has a lot of gaps, the state would be handled incorrectly. There would be one state item per matching grouping when data was present and they would only get moved forward if there was data for that key in a given interval. For intervals with no data, a no data line would get pushed through and have its own independent state. With this change, an empty group by result will push an empty data set through eval and it will now move the state buffers to allow for expiration and correct handling of subsequent intervals with data. If there is no resulting data lines from the overall expression, then a no data line for the overall expression will be emitted to the user. | 30 April 2019, 16:54:42 UTC |
| 4550be9 | brharrington | 29 April 2019, 21:47:02 UTC | detect empty state and stop tracking it (#1034) Updates the online algorithms used with stateful operators to detect if the state is effectively empty. In that case the state will be dropped from the state map maintained during evaluation. This is useful to avoid leaking memory for tracking the state during long running streaming evaluations. There are currently three exceptions that have an unbounded window and never become empty: ignore-N, sdes, and integral. Integral is generally not very useful in a streaming context so we may just prohibit that operation. For sdes (and ignore-N which is typically only used to align sdes), the current uses do not involve group by operations, so it shouldn't be an issue for now. We'll revisit in the future when there are concrete use-cases that are problematic for that operation. | 29 April 2019, 21:47:02 UTC |
| a805a6a | brharrington | 26 April 2019, 22:19:07 UTC | fix tag results on MemoryDatabase.execute (#1031) The set of tags for the aggregated lines should be limited to the set that are exact matches in the query or are a part of a group by. Otherwise the grouping can have incorrect duplicates in the result set. Fixes #629. | 26 April 2019, 22:19:07 UTC |
| cca15bb | brharrington | 26 April 2019, 22:09:09 UTC | expire interned queries after 12h (#1030) Switches from a ConcurrentHashMap to a Cache for the interned queries. This avoids a slow leak over time with churn in the set of queries. In practice, we have not seen enough churn for it to matter, but now queries that are no longer in use will expire and go away. Fixes #729. | 26 April 2019, 22:09:09 UTC |

| 180fbaa | brharrington | 25 April 2019, 02:26:33 UTC | improve handling of empty legend string (#1028) Before it would fail with an error that is hard for a user to understand: ``` IllegalArgumentException: Can't add attribute to 0-length text ``` This error would only show up if the image legend was rendered causing further confusion because it wouldn't show up if the legend was suppressed. Now it will fallback to the default legend string if an empty string is specified. | 25 April 2019, 02:26:33 UTC |
| b3206fa | brharrington | 25 April 2019, 02:19:29 UTC | remove inline rollup hooks on the api (#1027) Partially reverts #525. This removes the plumbing for the ids and rollups via the api. The usage for the internal DB have been retained. The reason for this is it adds additional complexity and risk to the backends and for most use-cases we are moving to the simple aggregator cluster instead (see atlas-aggregator in iep-apps). As we are not planning to exercise this as scale anytime soon, it is being removed from the APIs before 1.6 release. | 25 April 2019, 02:19:29 UTC |

Specifically: 1. The denominator for the average is the number of actual values, that is non-NaN entries, within the rolling buffer. The `:trend` operator always uses the window size which can create confusing drops because `NaN` values are effectively 0. 2. The minimum number of values permitted before emitting a mean can be specified by the user. 3. It is more consistent with other stateful operators in that it works on a window size relative to the step interval rather than a fixed time duration. 4. It is more consistent with similar operators in other tools such as the `rolling_mean` function provided by Panda. Fixes #958. | 29 January 2019, 22:30:29 UTC |

| d295803 | Matt Zimmer | 28 January 2019, 19:49:54 UTC | Throttle calls to CloudWatch (#983) We're hitting CloudWatch rate limits on a regular basis. However, the AWS limits should be sufficient for our overall per second call rate in the majority of cases. The current pattern of calls has bursts when the `Tick` message kicks off a collection, which causes the call rate to spike above the per second limit. This commit introduces call rate limiting to smooth out the request pattern. The Akka documentation for throttling request/response actor communication is incomplete. Through iteration playing around in a local toy app, I arrived at the implementation herein and confirmed that it works as expected. For this use case, it's important to ensure that either all or none of the `MetricMetadata` elements are added for processing. To satisfy that requirement, the full list is sent to the actor `Source` which then uses `flatMapConcat` to send each element individually through the throttle phase. This provides a stronger guarantee than the default, which could drop elements if the queue fills up. In practice, memory is more likely to be the limiting factor, given actors have unbounded mailboxes by default. Case in point, it was difficult to trigger the drop scenario in the local toy app. However, this approach more deterministically provides the stronger guarantee. | 28 January 2019, 19:49:54 UTC |
| c56bc88 | brharrington | 23 January 2019, 22:23:54 UTC | use jdk8 for building the scala 2.11 artifacts (#982) Since 2.11 doesn't support the `--release` option, building on a newer version can lead to errors when running on jdk8. Specifically the return type of some methods changed in jdk9+. This should fix errors like: ``` Cause: java.lang.NoSuchMethodError: java.nio.CharBuffer.clear()Ljava/nio/CharBuffer; at com.netflix.atlas.core.model.TaggedItem$.writePair(TaggedItem.scala:59) at com.netflix.atlas.core.model.TaggedItem$.computeId(TaggedItem.scala:105) ``` This means that image tests will not run for the 2.11 build. | 23 January 2019, 22:23:54 UTC |
| 8b8881f | brharrington | 18 January 2019, 17:40:54 UTC | remove stat vars from output tags (#981) The stat vars are desired for substitutions (#878), but should not be included in the tag maps for the output. The output tags should be stable over time if evaluated incrementally. Including the stats breaks this because the values are dependent on the data for that time slice. | 18 January 2019, 17:40:54 UTC |
| 55b900a | brharrington | 18 January 2019, 00:50:33 UTC | add helper function to validation a datasource (#980) This can be used as an upfront check to filter out bad data sources rather than getting the failure via the stream. | 18 January 2019, 00:50:33 UTC |
| b014def | brharrington | 08 January 2019, 21:13:50 UTC | update default grid colors (#979) This makes the grid colors lighter so they do not distract the viewer as much. These settings have been used internally for many years so this also reduces differences between the internal use at Netflix and OSS settings. | 08 January 2019, 21:13:50 UTC |
| e10c574 | brharrington | 04 January 2019, 19:20:31 UTC | use dedicated object for algo state (#978) Before it was using a Config object for convenience. This switches it to a dedicated object that can be easily used with `Json.encode/decode` or other similar tools. This should also be more efficient for the more common use-cases because we can avoid creation of the needless config objects. | 04 January 2019, 19:20:31 UTC |
| 14efd74 | brharrington | 04 January 2019, 00:43:09 UTC | avoid conversion if already a ConfigValue (#977) In the docs site it is getting config 1.2 in the sbt classpath. There isn't an obvious way to force it to a newer version. The older version will fail if trying to convert a ConfigValue to a ConfigValue. For now we can workaround the problem by special casing that to avoid the unnecessary conversion. | 04 January 2019, 00:43:09 UTC |
| 87689ad | brharrington | 03 January 2019, 21:52:59 UTC | set --release for javac (#976) After switching to use jdk11 for the build, the java classes were getting compiled to class version 55 instead of 52. | 03 January 2019, 21:52:59 UTC |
| bb7b319 | brharrington | 03 January 2019, 20:43:24 UTC | remove redis from travis config (#975) This is no longer needed for the Atlas build. | 03 January 2019, 20:43:24 UTC |
| c9cad18 | brharrington | 03 January 2019, 19:24:13 UTC | disable scaladoc publishing (#974) On JDK11 with `-release 8` it crashes with: ``` [error] java.lang.AssertionError: assertion failed: [error] type AnyRef in java.lang [error] while compiling: ... [error] during phase: globalPhase=terminal, enteringPhase=typer [error] library version: version 2.12.8 [error] compiler version: version 2.12.8 ``` This is a quick workaround as we do not rely on the published scaladoc jars for anything. | 03 January 2019, 19:24:13 UTC |
| ceced7a | brharrington | 03 January 2019, 17:32:11 UTC | build using openjdk11 (#973) This updates the travis builds to use OpenJDK 11. The `-release 8` option is used to ensure the generated bytecode will still work on JDK8. Due to font rendering differences, image tests will fail when running on older versions of the JDK or on operating systems other than Mac OS X. Those checks will now automatically be disabled on systems that are known to fail, but are checked as part of CI validation. | 03 January 2019, 17:32:11 UTC |
| f6c0fb9 | brharrington | 02 January 2019, 22:25:02 UTC | enable antialiasing by default (#972) Update the config settings to use antialiasing for the text by default. It is explicitly disabled for tests as it will frequently cause rendering differences across systems. | 02 January 2019, 22:25:02 UTC |
| 822beec | brharrington | 02 January 2019, 21:14:58 UTC | use RobotoMono font for error images (#971) Follow up to #967. Use RobotoMono font for the png error image utility as well as the graphs. | 02 January 2019, 21:14:58 UTC |
| 4c10f3c | brharrington | 02 January 2019, 18:35:26 UTC | sbt 1.2.8 (#970) Fixes occasional NPE for Bintray. https://developer.lightbend.com/blog/2018-12-30-sbt-1-2-8/ | 02 January 2019, 18:35:26 UTC |
| 34d291b | brharrington | 02 January 2019, 18:05:06 UTC | update license headers for 2019 (#969) | 02 January 2019, 18:05:06 UTC |
| de117e9 | brharrington | 22 December 2018, 04:39:47 UTC | use standard IIOMetadata classes for PNG (#968) When using the `-release 8` option the internal `PNGMetadata` class is not found in the classpath. Update the usage to rely on the public APIs. | 22 December 2018, 04:39:47 UTC |
| 363f2fe | brharrington | 21 December 2018, 23:49:17 UTC | switch to RobotoMono font (#967) The Lucida fonts are not included with OpenJDK and have been removed from OracleJDK in version 11. The RobotoMono family is Apache licensed and will now be used as the default to get a more consistent experience across JDK versions. | 21 December 2018, 23:49:17 UTC |
| 4662ced | brharrington | 21 December 2018, 21:08:31 UTC | fix #852, inconsistent group by behavior (#966) Before, attempting a group by on non-grouped expressions without a math aggregate function would behave differently than a non-grouped expression with a math aggregate. Now they have the same behavior and the group by will be ignored for expression trees that do not support it. | 21 December 2018, 21:08:31 UTC |
| 22ae17f | brharrington | 21 December 2018, 20:32:32 UTC | fix #763, custom consolidation with rewrites (#965) The rewrites that look like aggregation functions will now work with custom consolidations. If used the rewrite will not be preserved in the model. So the output of converting the parsed expression model to a string will be the expanded expression and not indicate the rewrite was used. | 21 December 2018, 20:32:32 UTC |
| 19bcfc0 | brharrington | 21 December 2018, 19:01:14 UTC | fix #948, all zeros shown on y-axis (#964) If the upper bound exactly matched `10 * factor` for the selected unit prefix, then it would use a different selection to avoid large numbers for the tick labels. However, for an exact match it is better to use the default prefix to avoid getting zeros due to rounding with the larger prefix. | 21 December 2018, 19:01:14 UTC |
| c4e8820 | brharrington | 21 December 2018, 17:31:14 UTC | move PngImage from atlas-core to atlas-chart (#963) The image utilities are only used for charting and this makes it easier to get consistency with upcoming font changes. | 21 December 2018, 17:31:14 UTC |
| b2a28d0 | brharrington | 21 December 2018, 03:36:00 UTC | akka-http 10.1.6 (#961) Adds an explicit `akka-stream-testkit` dependency because it is no longer included with `akka-http-testkit`. | 21 December 2018, 03:36:00 UTC |
| a8d0eed | brharrington | 20 December 2018, 20:55:28 UTC | update to jackson 2.9.8 (#960) Has a number of security fixes: https://groups.google.com/forum/#!topic/jackson-user/8jdpNS1dQPQ https://github.com/FasterXML/jackson/wiki/Jackson-Release-2.9.8 | 20 December 2018, 20:55:28 UTC |
