Hi Cody,

Are you able to restart MaDDash or does it immediately crash on boot? It looks like it is having problems connecting to the embedded database it uses to track the alert history. If maddash runs after a restart of the service, it may have just temporarily lost its connection for some reason.

If it won’t come back up, there are a couple things you can do. For one, you might want to double-check your disk isn't full since that can cause problems for the embedded database it uses. If the disk is fine, you will likely need to remove the data of the database. Doing so will NOT destroy any measurements since MaDDash does not store those. It will destroy the last 7 days of alert history (i.e. whether a check was red, orange, green, etc). The commands to do so are as follows:

/etc/init.d/maddash-server stop
rm -rf /var/lib/maddash/data/*
/etc/init.d/maddash-server start

Hope this helps,
Andy

Hello,

 

Recently our Maddash server has ran into some complications. While the toolkit side of the node is exhibiting no issues, testing seemingly isn’t effected , and I believe I have found the cause of the issue.

 

# systemctl status maddash-server

maddash-server.service - MaDDash Scheduler and REST Server

                Loaded: loaded (/usr/lib/systemd/system/maddash-server.service; enabled; vendor preset: disabled)

                Active: failed (Result: exit-code) since Sun 2018-08-05 15:44:15 EDT; 18h ago

               Main PID: 1287 (code=exited, status=1/FAILURE)

 

So, looking into the /var/log/maddash/maddash-server.out file, we see this:

 

Initialization error: Connections could not be acquired from the underlying database!

java.lang.RuntimeException: Connections could not be acquired from the underlying database!

Has anyone else ran into this issue? ( Or, it’s entirely possible this is a redherring. )

 

Best,
