Description
Hi there!
I have mariadb cluster with 5 nodes and one maxscale-node... and some troubles with monitor (script-trigger) [doc. example
[max_monitor]
|
type=monitor
|
module=mysqlmon
|
servers=max-1,max-2,max-3,max-4,max-5
|
user=maxscale
|
#script=/usr/local/sbin/failover.py --logpath=/var/log/maxscale --event=$EVENT --initiator=$INITIATOR --nodelist=$NODELIST --ignorenodes=max-3,max-4,max-5 --repluser=replica -d
|
script=/usr/local/sbin/test_length.sh --event=$EVENT --initiator=$INITIATOR --nodelist=$NODELIST --very_long_string1=000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 --very_long_string2=000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

passwd=maxscale
|
monitor_interval=10000
|
events=master_down
|
detect_stale_master=true
|
detect_replication_lag=true
|
#detect_stale_slave=true
|
The trouble is - script string with arguments is truncated when it executed. Debug script and logs attached:
# cat /usr/local/sbin/test_length.sh
|
#!/bin/bash
|
echo $* > /tmp/test_length
|
|
|
# maxscale.log

I can't find in documentation about this limitation. It's very critical and important for me, cuz on my prod i use long DNS mysql server names :'(
Could you please remove this limitation, or defined it into documentation?
