Sensu plugins on clients
OK, for the Sensu addition yesterday it turns out that two Sensu
plugins are also needed on clients:

and then the new Sensu client is all green.
Getting rid of a Sensu check
This is surprisingly difficult. Yesterday I switched cranlogs.r-pkg.org to HTTPS, after getting a new certificate for it. It seems to work fine now, I don’t know what was the problem last time (https://github.com/metacran/cranlogs.app/issues/22), but it works fine today.
I also updated the Sensu checks for cranlogs, to check HTTPS and also the HTTP -> HTTPS redirect. It seems that to get rid of the old check, one has to restart the Sensu server and the client as well, both running on monitor.r-hub.io in this case.
Also, one needs to put the port number into the check. Even if the nginx redirect header does not have it: https://cranlogs.r-pkg.org:443/downloads/daily/last-week/igraph
Azure disk attach/detach
This seems to a straightforwars enough operation, but it is not. Make sure that you close the browser tab, and open a new one to Azure, after each detach/attach operation, because the UI does not refresh the state of the disk. It is actually the same for the state of the virtual machine, you click on Stop, it stops (after some time), but the state is never updated, until a new browser UI window is used.
I wonder who thought this was a good idea. It only took me ~4 hours to solve this, thank you.
Fedora update
Finally I fixed the Docker builds in cran.r-hub.io, and built new Fedora images. (https://github.com/r-hub/rhub-linux-builders/pull/12#issuecomment-247629893)
In the process of brushing up Jenkins, I made sure that I get emails about failures, both from cran.r-hub.io and jenkins.r-pkg.org. For this one needs to install postfix, and on jenkins.r-pkg.org, one also needs to allow the Docker subnets in the main.mf postfix config file, because there Jenkins runs in a container.
The only glitch is that the clang image does not build, because I would need another external clang repository for that. :(
Dokku update on metacran
I updated Dokku to the latest stable version (0.7.1) on r-pkg.org. This affects cranlogs.r-pkg.org, rversions.r-pkg.org, crandeps.r-pkg.org as well. The new version uses the new plugins for Redis and PostgreSQL as well.
