Hello. This is Igarashi (
id:masarasi), the Mackerel team CRE. We are pleased to announce our next update.
- We added units that can be selected in the custom metrics graph definitions.
- You can now select 6M (six months) as the display period for graphs.
- We added metric targets that can be retrieved through ElastiCache using AWS Integration.
- We added Ubuntu 22.04 LTS to our supported OS list.
- We made changes so that apt-key warnings are not displayed in the new host registration commands on Ubuntu / Debian.
- We fixed a bug that prevented the mackerel-plugin-docker from getting metrics on OS with cgroup v2.
We added units that can be selected in the custom metrics graph definitions.
The following are new choices available in graph definition units. Please use them to post metrics such as network bandwidth and response time.
- seconds
- milliseconds
- bits/sec
Please note that this function only changes the display. The metric values will not be converted to the selected units. For example, if the original value is 3000ms (unit: milliseconds) and you change the unit to seconds, it will be displayed as 3000s.
Mackerel uses seconds as its standard unit for time. We recommend that you use seconds when developing new plugins.
Graph definitions can be changed using the gear icon in the upper right corner of each custom metric graph on the host details screen.
You can now select 6M (six months) as the display period for graphs.
The display period for graphs that you could choose on the graph controller was 1M (one month) followed by 1Y (one year). We have now added a 6M (six months) option. This option for information on medium-term trends.
We added metric targets that can be retrieved through ElastiCache using AWS Integration.
As recently announced, we have added additional metric targets that can be retrieved through ElastiCache using AWS Integration. New authentication and bandwidth limitation metrics are available.
Redis's GlobalDatastoreReplicationLag, which we previously announced, will not be implemented. Please refer to the help information below for information on the metrics you can currently obtain through ElastiCache.
We added Ubuntu 22.04 LTS to our supported OS list.
We added Ubuntu 22.04 LTS to our supported OS list. Please refer to the help information below for the currently supported Mackerel environments.
We made changes so that apt-key warnings are not displayed in the new host registration commands on Ubuntu / Debian.
When running the command to register new hosts on newer versions of Ubuntu / Debian, users were getting apt-key warnings when installing the Mackerel agent. apt-key is deprecated, we added changes to the alternative command so that no warning is displayed.
We fixed a bug that prevented the mackerel-plugin-docker from getting metrics on OS with cgroup v2.
We fixed a bug that prevented the mackerel-plugin-docker from acquiring metrics on OSes that use cgroup v2 (Debian 11, Ubuntu 22.04, etc.). In conjunction with this fix, we removed the implementation of metric acquisition for older Dockers. Metric retrieval using --method File is no longer supported in versions later than those shown below. If you are currently using one of these versions and wish to upgrade, please review your settings.
- mackerel-agent-plugins 0.72.0
- mackerel-agent Docker image 0.72.14
The metrics available for cgroup v1 and cgroup v2 OSs are different. See the Readme below for details.
This fix was corrected by a PR from a user. I would like to take this opportunity to express my gratitude.
