Graph widgets for custom dashboards can now display a fixed vertical axis, and more

Hello, this is Igarashi (id:masarasi), the Mackerel team's CRE. The details of this update are as follows.

Graph widgets for custom dashboards can now display a fixed vertical axis

Graph widgets can now display a fixed vertical axis with a range of arbitrary minimum and maximum values. loadavg, for example, can cause the maximum value of a graph to vary depending on metric values, making it difficult to compare graphs from different hosts. With this update, the vertical axis of graphs can now be fixed, making it easier to make comparisons.

Also, setting a negative value for the minimum value will allow metrics with negative values to be plotted on the graph, which may be useful for some users.

The fixing of the vertical axis of a graph will continue to apply even when the graph is displayed in full-screen mode. Input via the Graph Widget API is also supported. We hope you will take advantage of this improved graph widget functionality.

[Preview of future changes] Specification changes will be made to check-ntservice

check-ntservice, which is bundled with mackerel-agent for Windows, will undergo the following specification changes in a future upgrade.

  • If no service matching the criteria specified in '--service-name' is found, the monitoring results returned used to be normal (OK). After the update, this will trigger an "UNKNOWN" alert.
  • If multiple services matching the criteria specified in '--service-name' are found, the results of the last service checked used to be reported. After the update, the results of the first service matched will be returned.
  • If the monitoring results are normal, the results message returned used to be only "NtService OK:". After the update, the message returned will be in the format "NtService OK: ServiceName: Caption - Running".

We will notify you again when the specification changes are completed. Users who are using "check-ntservice" are advised to review the above changes in advance and upgrade to the new version following its release.

[Preview of future changes] Support for Windows Server 2012 and Windows Server 2012 R2 will be discontinued

Security support for Windows Server 2012 and Windows Server 2012 R2 will be discontinued on October 10th, 2023. Mackerel will also discontinue support for these OS along with the end of security support by Microsoft.

While Microsoft offers the Extended Security Updates Program, please note that Mackerel will not be providing support even during the duration of this Extended Security Updates Program.
