Dashmate users that want to stop their Dashmate in order to update their Core version, or update their Dashmate version or do server Maintenance or want to do a server reboot, first need to check if their Evonode/Masternode is currently not involved in any LLMQ quorum, that give high PoSe Penalty scores when interrupted. To avoid these high PoSe Penalty scores or PoSe bans (interrupting two llmq quorums = Instant PoSe ban), the following shell script can be created and used to fetch this directly from Dashmate core.log

Step 3 : Save as posecheck.txt
Step 4 : Rename to posecheck.sh
Step 5 : Transfer this file to your Ubuntu home directory (i use WinSCP for this)
Step 6 : chmod +x posecheck.sh
Step 7 : dos2unix posecheck.sh
(if dos2unix not installed, then install through sudo apt-get install dos2unix but on my Ubuntu system it was already installed)
Step 8 : ./posecheck.sh
'./posecheck.sh' command can now be used to have above commands in shell script executed automatically, with 1 second between each command.
Output :
Output handling for user :
* Be informed that llmq_60_75 needs to end with [31], if there is a lower number then wait and check from time to time untill it reached [31].
You should get a warning if the script does not find [31], urging you to not interrupt it.
* Use 'blocks to go before quorum restart' to see when is an opportune moment to stop your Masternode / Evonode, so you avoid getting hit with PoSe scores when llmq quorums get restarted again and possibly try to select your Masternode/Evonode, while Dashmate or dashd is still down on your server.
* Best viewed on a maximized PUTTY window
Same can be done with a Masternode / Evonode that has not been setup through Dashmate, but you will need to adjust both the path and the filename (~/.dashcore/debug.log ??) in above mentioned shell script, as logs from Dashmate differ in name and path.
