This change updates the default pattern to just extract the prefix and ignore the counter at the end. So activity for all stream supervisors will show up as a single metric. | 01 August 2017, 17:29:49 UTC |

0d373a1 | brharrington | 28 July 2017, 18:14:16 UTC | add helper for simple shard mapping (#637) Move over the internal helper utility for mapping data to a set of instances. This is typically used with a service like edda that maintains stable slotting for instances within auto-scaling groups. These simple schemes are preferred for the core monitoring system to avoid dependencies on complex infrastructure like zookeeper that are prone to having correlated failure with the key systems we need to monitor. | 28 July 2017, 18:14:16 UTC |

The distinction between these is usually something the user doesn't need to worry about, but sometimes causes confusion. | 26 July 2017, 23:51:37 UTC |
61de4f0 | brharrington | 22 July 2017, 16:34:59 UTC | add mappings for application load balancer stats (#634) Adds basic mappings for the ApplicationELB metrics in CloudWatch. There was a bit of debate on whether the LoadBalancer and TargetGroup dimensions should be kept as is or extract the name and only show that. The ids are rarely useful to the end user and add quite a bit of noise when selecting in the UI. For now though we just map the values in as they are provided in CloudWatch. | 22 July 2017, 16:34:59 UTC |

Improves the error message returned if the input URI is missing required parameters. It has also been changed to get returned as a diagnostic message as part of the stream so that a single bad URI will not stop the processor for all evaluations. | 13 July 2017, 22:17:14 UTC |

Sample exception below: ``` java.util.NoSuchElementException: head of empty list at scala.collection.immutable.Nil$.head(List.scala:428) ~[scala-library-2.12.2.jar:?] at scala.collection.immutable.Nil$.head(List.scala:425) ~[scala-library-2.12.2.jar:?] at com.netflix.atlas.chart.graphics.Ticks$.time(Ticks.scala:265) ~[atlas-chart_2.12-1.6.0-SNAPSHOT.jar:1.6.0-SNAPSHOT] ``` The cause is that there were no options for meeting the desired number of major ticks given the options for timeTickSizes. This change uses a simpler selection method with just major ticks for longer ranges setting it to the name of the month or year. | 29 June 2017, 16:34:41 UTC |
be4cd8b | brharrington | 20 June 2017, 18:05:17 UTC | add :clamp-min and :clamp-max (#623) Allows the user to restrict the min and max values of the input respectively. The most common use-case motivating this is to be able to support a bounded auto-scaling for data on an axis. The axis lower and upper limits are either explicit or automatic. These operators give more flexiblity and can be set for a given line to tune its behavior. Name was chosen to match the same operators in Promoetheus. | 20 June 2017, 18:05:17 UTC |
1b4d0aa | brharrington | 19 June 2017, 15:17:12 UTC | cache most recent datapoints from cloudwatch (#621) In some cases if there are a lot of cloudwatch metrics, then the polling can start to get throttled and cannot keep up at the desired rate. This can cause spotty reporting until the limit can get raised or the poller config is changed to be less aggressive. To minimize the visibility pf the problem for a user consuming the metric the last datapoint is now cached and the reported value comes from the local cache. This does mean that when such a problem is happening the wrong value might be propagated for several minutes. From recent testing though in the more typical case it avoids confusion more often until there is a better way to access cloudwatch data. If it is a big concern the ttl can be configured to a smaller value. | 19 June 2017, 15:17:12 UTC |

That is nothing will ever write to it again. The variants with a Long key type use an internal buffer to avoid allocations when passing the long value to `MurmurHash3.bytesHash`. The multi-threaded access could result in errors such as BufferOverflowException on the buffer. This changes those collections to use a ThreadLocal for keeping track of the buffers. | 31 May 2017, 01:28:26 UTC |
36f537c | brharrington | 30 May 2017, 15:41:04 UTC | update findKeys to just return the strings (#602) Before it was wrapping the string in a TagKey type that could also provide counts for each key. Since this isn't supported or used anymore we can avoid the additional allocations. Also most use-cases were just mapping it back to strings after getting the response. | 30 May 2017, 15:41:04 UTC |
3864010 | brharrington | 29 May 2017, 21:51:01 UTC | improve tag query performance (#601) Drops support for counts in the index and does some initial work to simplify and improve performance. For a lot of the common use-cases we see a 2-3x improvement: **Before** ``` Benchmark Mode Cnt Score Error Units create thrpt 10 13.210 ± 1.041 ops/s findKeysAll thrpt 10 4646.344 ± 176.685 ops/s findKeysQuery thrpt 10 450.728 ± 39.296 ops/s findValuesAllMany thrpt 10 739.919 ± 41.530 ops/s findValuesAllOne thrpt 10 2194.050 ± 248.351 ops/s ``` **After** ``` Benchmark Mode Cnt Score Error Units create thrpt 10 20.270 ± 0.798 ops/s findKeysAll thrpt 10 6382544.499 ± 353321.426 ops/s findKeysQuery thrpt 10 1118.262 ± 370.960 ops/s findValuesAllMany thrpt 10 3849.128 ± 416.156 ops/s findValuesAllOne thrpt 10 4485.419 ± 424.741 ops/s ``` Some of the primitive collections have also been adjusted to use murmur hash instead of `Long.hashCode(v)` because the collision rate was way to high. This adds a bit of memory overhead because we copy the value into a pre-allocated byte buffer to reuse the murmur hash implementation provided in the scala std library. | 29 May 2017, 21:51:01 UTC |
51f676b | brharrington | 27 May 2017, 18:10:52 UTC | drop cross build for 2.11 (#600) We have been running on 2.12 for a while now and internal builds and deployments are mostly on 2.12 now. The few stragglers are using the 1.5.x Atlas builds which is 2.11.x only and that will not change. | 27 May 2017, 18:10:52 UTC |
73416e3 | brharrington | 27 May 2017, 18:01:53 UTC | always sort NaN values to the end (#599) This change alters the behvaior of sorting to always move NaN values to the end regardless of the order. Before, NaN values were at the end for ascending order and descending order would just reverse the list causing NaN values to show at the top. Fixes #586. | 27 May 2017, 18:01:53 UTC |

46a5fb2 | brharrington | 23 May 2017, 17:01:54 UTC | avoid unused method warnings in guice modules (#594) Since scala 2.12 the private provider methods in the module cause warnings about unused methods. Unfortunately scala doesn't provide a way to suppress these on individual methods (SI-1781). For now the work around is to mark them as protected rather than private. Note the module class is final so there will not be any subclasses. | 23 May 2017, 17:01:54 UTC |
42de1e4 | brharrington | 23 May 2017, 16:50:43 UTC | update flow types to allow DiagnosticMessages (#593) Updates the high level processor to pass JsonSupport messages instead of TimeSeriesMessage specifically. This gives a lot of flexibility to send through other types like DiagnosticMessage or other helpful information when processing the stream. | 23 May 2017, 16:50:43 UTC |

95665c5 | brharrington | 17 May 2017, 21:22:41 UTC | fix unit used when paritioning a context (#588) The context was ignoring the unit parameter passed into partition. This would result in an IAE under some situations. See test case for more details. | 17 May 2017, 21:22:41 UTC |
39f9d30 | brharrington | 16 May 2017, 16:13:11 UTC | initial port of fetch api (#585) Starting work on #547. This adds an endpoint compatible with the internal fetch API to the oss repo. There are still a number of things left to do, but this should unblock some other efforts. To be addressed in later PRs: - Test coverage, there are some basic test cases but I still need to debug some issues with one of them and clean them up a bit to remove use of some test data that was dumped from internal sources. - The throttling/limiter logic still needs to be moved over, but is a bit more intertwined. - In general need to move the actors away from the actor publisher that was deprecated in akka 2.5. | 16 May 2017, 16:13:11 UTC |

26239b2 | brharrington | 05 May 2017, 04:02:25 UTC | create bitmap directly instead of through int set (#573) The use of the int set was a carry over from the lazy set implementation. This removes some steps saving memory and computation cost when building the index. | 05 May 2017, 04:02:25 UTC |

f2edd36 | brharrington | 01 May 2017, 22:19:52 UTC | included rendered image in v2.json response (#568) Fixes #564. We may move this behind a flag before 1.6 final, but for now it is enabled by default. By including in the v2.json format the UI/dashboard can use the static image and switch to a dynamic rendering without making another request. The message has a type of `graph-image` with a data field that is a data uri of the image without the legend. Sample usage: ```html <html> <body> <div id="content"></div> <script> var content = document.getElementById('content'); fetch('http://localhost:7101/api/v1/graph?q=name,sps,:eq,(,nf.cluster,),:by&format=v2.json') .then(function(response) { return response.json(); }) .then(function(json) { var html = ''; json.forEach(function(msg) { if (msg.type === 'graph-image') { html += '<div><img src="' + msg.data + '"/></div>'; } else if (msg.type === 'timeseries') { html += '<div>' + msg.label + '</div>'; } }); content.innerHTML = html; }); </script> </body> </html> ``` | 01 May 2017, 22:19:52 UTC |
