Modified signature #42

Closed schall1337 closed 2 years ago

schall1337 commented 2 years ago

Hi, after installing the plugin and restarting Grafana I get the message "Modified signature". Windows 10, Grafana v8.2.5 (b57a137acd) How can i fix this? Cheers

crazycto commented 2 years ago

Yeah, troubleshooting #41 i got that as well...

@srclosson Is this related to the work done on the last release?

JoeH20 commented 2 years ago

Anytime I modify the grafana.ini file and restart the service the plugin is disabled for "Modified signature".

Currently running Grafana on windows

Are there any updates on this issue?

sleiban commented 2 years ago

@JoeH20 As a workaround untill the next release is ready (hopefully soon now), you can delete the MANIFEST file for the plugin and allow for unsigned plugin.

In Custom.ini, add the following under [plugins] section: allow_loading_unsigned_plugins = grafana-opcua-datasource

srclosson commented 2 years ago

This should now be fixed. Would you try the latest 1.1.5 release and respond back?

OPC_PLUGIN

Looks like I have the same issue.

sleiban commented 2 years ago

This is strange. How do you install this plugin? Are you cleaning up any existing folders containing this plugin? Do you download from https://grafana.com/grafana/plugins/grafana-opcua-datasource/?tab=installation ? Then extract it to C:\Program Files\GrafanaLabs\grafana\data\plugins ?

schall1337 commented 2 years ago

For me the modified signature seems now to be resolved, though when i try to test the plugin as a datasource i get the message "plugin health check failed".

srclosson commented 2 years ago

In that case, something else is usually going on. Have you looked at the logs @schall1337? Another idea is to run the plugin from the command line. In c:\Program Files\GrafanaLabs\grafana\data\plugins\grafana-opcua-datasource run gpx_opcua_windows_amd64.exe I'd be interested in the output from this.

these are the logs @srclosson

i think this error "Server did not return an EndpointDescription that matched the one used to create the secure channel." causes the issue for me, but seems it has something to do with the opc server not the plugin.

edit: changed in the url the localhost to real ip now it works
