appdstatus.sh: Events-service liveness-detection fragile and broken in 4.4(?)+ (4.5.1 confirmed)

Issue 1): EC allows installation of events service to any location-
Issue 2): "Events Service" process signature changed from "events_service" to "events-service"
(underscore to hyphen)

Liveness script checks for it in the "usual" <=V4.3 spot (fails)

bash -x output:

`+ events_running
+ grep /data/appdynamics/platform/product/controller/events_service
+ grep java
+ ps -f -u appd
+ return 1
+ case $? in
+ echo 'events service not running'
events service not running`

Events service doesn't live there, events service lives here:

/data/appdynamics/platform/product/events-service/processor/bin/

Process signature:

Kinda lame fix/hack:

HA/lib/status.sh:

`function events_running {
# scosol fix
# if ps -f -u $RUNUSER | grep "java" | grep "$APPD_ROOT/events_service" >/dev/null ; then
if ps -f -u $RUNUSER | grep "java" | grep "events-service" >/dev/null ; then`
