All the flavors of plugins

You can see the complete list of available plugins in the following link:

https://grafana.com/grafana/plugins/.

The plugins are classified into several categories, depending on various factors. Let’s explore them.

Signed versus unsigned plugins

Grafana validates each plugin by means of a signature. Grafana uses this signature for verifying that a plugin is original and has not been modified.

When Grafana starts, it checks the signature of each of the plugins in the plugin directory. If a plugin is not signed, Grafana will not load it.

You can see the verification of the plugins by going to the Configuration | Plugins page.

There are several statuses for the signature of a plugin:

• Core: When the plugin is included in the Grafana code.
• Invalid signature: When the plugin doesn’t have a valid signature.
• Modified signature: When the plugin suffered modifications after its signature. This can be a security issue...
