My name is Dishi, and I work on Sensu at Sumo Logic. Thank you for reaching out regarding the -m (magic) option in the sensu-plugins/sensu-plugins-disk-checks plugin used to adjust thresholds based on disk size.
I have replicated the issue in my lab environment and confirmed that the -m option for adjusting thresholds based on disk size is not working as intended.
The challenge is that this plugin is part of the community tier, not a Sensu/Sumo Logic company-owned resource. We directly manage our company-owned resources, while the community manages community resources such as sensu-plugins. Our ability to address it directly is limited. Adding an issue to the repository in GitHub may be a way forward. The community actively contributes to improvements and fixes. Another benefit of this community is that other members may have solved this problem and contributed a solution here.
Another approach you may consider is utilizing two or more checks with subscriptions for each of the class of entities represented by the hardware differences, for example, using the much more recent Go asset:
Check one: Build this check for your large drives and have it alert at 10% disk remaining.
Check two: Check smaller drives, for example, 20%.
Lastly, subscribe the Agent entities to these checks as appropriate?
I hope that’s helpful. If you have any further questions or need assistance with other aspects of Sensu, please don’t hesitate to continue posting. The community is here to support you and help you navigate any challenges you may encounter. You are not alone in this journey.
Appreciate the detailed response. I will look into your suggested approaches to address my requirement. I’m still new to the Sensu world so was not aware of where the correct place is to post questions. I will also add an issue to the repository in GitHub. How do I tell if a plugin is part of the community vs company owned resources?
To distinguish between community vs. company-owned resources, you can visit Bonsai: https://bonsai.sensu.io/. Bonsai is a repository where you can find pre-built Sensu plugins, checks, handlers, and more. It simplifies adding and managing these tools in your Sensu setup, allowing you to quickly integrate new features with a simple command.
In Bonsai, assets are labeled under two tiers: Community and Supported. Supported tier plugins are officially maintained by Sensu, ensuring regular updates and support, while Community tier plugins are maintained by the community of users and contributors. This distinction helps you understand the level of support and maintenance for each asset.
