Following are notes for version 4.0.0.2 of the UnboundID Metrics Engine. Notes for the following versions of the Metrics Engine are also available in this document:
The following issues have been resolved with this release of the Metrics Engine:
Fix an issue where dsconfig could apply changes to multiple servers in a failure situation even though it claimed that no changes were applied. Issue:DS-8677
These features were added for version 4.0.0.0 of the Metrics Engine:
Update the names of the UnboundID-branded products, which are now:
The Metrics Engine can now be configured to monitor and alert on Service Level Agreements. For information about Service Level Agreements and how to configure them, please refer to the "Monitoring Service Level Agreements" section of the UnboundID Metrics Engine Administration Guide.
Provide API for accessing Metrics Engine SLAs and Threshold Alerts. For API documentation, please refer to the "Accessing the Metrics Engine Data" chapter of the UnboundID Metrics Engine Administration Guide.
These were known issues at the time of the release of version 4.0.0.0 of the Metrics Engine:
Version 3.6.x Metrics Engine cannot monitor version 4.x servers. To monitor a version 4.x server you must first upgrade the Metrics Engine to version 4.0. Issue:7743
These issues were resolved with version 4.0.0.0 of the Metrics Engine:
File Server HTTP Servlet Extensions now allow a default MIME type to be set with the default-mime-type property. Issue:DS-6959
Change the stop-* tools to behave like other task based tools. These tools require the use of the --task argument to ensure that user knows they are using a server task. These tools also will not use properties files unless you provide the --usePropertiesFile or --propertiesFilePath arguments.
Fix a bug that prevented viewing hidden and complex configuration properties using dsconfig in a non-interactive mode. Issue:DS-7245
Fix a bug in the manage-extension tool that would cause an error when attempting to install an extension if that extension's getExtensionDescription method returned null (which is allowed as per the documentation). Issue:DS-7367
Fix a bug in the LDAPConnectionHandler where it did not close the NIO Selector on shutdown. On some platforms this caused the underlying socket channel to remain bound, which prevented the server from being able to restart. Issue:DS-7373
These features were added for version 3.6.0.0 of the Metrics Engine:
IPv6 is now a supported deployment option.
64-bit JDK 7 is now a supported deployment option, but 32-bit JDKs are no longer supported.
Provide API for accessing monitored server Alerts.

These issues were resolved with version 3.6.0.0 of the Metrics Engine:
Fix a typo in the output of "query-metrics explore". It had indicated that "&dimensions=application-name:value1,value2" could be used to restrict the query output, but it should just be "&dimension=application-name:value1,value2" (not plural). Issue:DS-7226
Added HTML response to the chart resource using the URL /api/v1/metrics/{metricId}/chart.html. The title of the HTML document will be the same as that of the chart title. Issue:DS-7071
Fix a problem in the manage-extension tool where it would fail on Windows because it tried to delete some temp files that were currently in use. Issue:DS-6770
The default behavior of the API is changed to address how incomplete sample intervals close to the current real time are returned when performing a multi-time interval query:
- The datatable and chart resources now truncates incomplete time intervals from the data by default but only up to 5 min worth of intervals or 20% of the total number of intervals, which ever is less. - Introduced the lastCompleteIndex property to the data series objects in a dataset response. This is used to indicate the index of most current 'complete' sample where a complete sample is a sample that contains values for all aggregates. No data is truncated by default. - The default trimming behaviors of all resources may be overridden using the new maxTruncatedIntervals query parameter. This allows the client to specify the maximum number of incomplete sample intervals that may be truncated from the resulting response. Issue:DS-7068
Added a new includeEmptySeries query param to the datatable and chart resources that may be used to control whether the results should contain series with no data. The default is false. Issues:DS-7071,DS-7077
Fix a bug in dsconfig that prevented going back when adding a new configuration object inside of an existing one. Issue:DS-7263 SF#:1793
Prevent disk space monitoring for metrics db for environments where file permissions disallow reading. Issue:DS-7266 SF#:1794
Add a few query parameters to the chart resource (/api/v1/{metricId}/chart) to allow customizations:
- title: The input is now treated as a Velocity template and the $metric context may be used to reference anything in the Metric object. - subTitle: Allows adding one or more sub-titles to the chart. Velocity templates may be used. - tz: Specifies the time zone used for all date/times on the chart. Default is GMT. - dateFormat: Specifies the format of the all date/times on the chart. It uses the standard Java SimpleDateFormat strings. - useLogScale: Use a logarithmic scale for the range axis. - style: Allows customizations of various stylistic elements in the chart in a psudo CSS format (semi-colon separated list of rules where the key and value separated by a colon). The following rules are implemented: -- series-color: A space separated list of colors to use for the different series in the order specified. The standard 17 CSS named colors are supported along with the hex (ie.#445566) and rgb (ie. rgb(45, 100, 255)) notations. (ie. series-color: blue red #221122 rgb(234,255,255);) -- series-width: The width of the series lines in px notation (ie. series-width: 5px;) -- background-color: The background color of the chart (ie. background-color: white;) -- grid-line-width: The width of the gridlines. If only one value is present, both the domain and range gridlines will use the same width. Otherwise, the first value is for the domain and the second for the range gridlines. (ie. grid-line-width: 4px 6px;) -- grid-line-color: The color of the gridlines. (ie. grid-line-color: red blue;) -- legend-position: The position of the legend, if present. (ie. legend-position: right;) Issue:DS-7076
These features were added for version 3.5.1.0 of the Metrics Engine:
The Metrics Engine is a core server product that collects and aggregates key diagnostic, capacity, and usage information from an UnboundID server topology consisting of instrumented Directory Server, Directory Proxy Server, and Synchronization Servers running release 3.5.0.0 and above. Metrics data can be explored and graphed using the included query-metric tool, and the Metrics Engine REST API makes this information available to custom applications and third-party systems. To learn more about the Metrics Engine, please refer to the UnboundID Metrics Engine Administration Guide.
