Check RPA hub health

Use the RPA Manager API for a health check: RPA_MANAGER_HOST:5555/api/healthcheck/.

Below is a sample health check for cases when RPA hubs are unavailable:

The following script can be used to check whether all hubs registered in the quota are up and running. If SSL is not configured, use http instead of https.

$ cat ./check_hub.sh

#!/bin/bash
APPALL=`find /opt/workfusion/ -type d -name app-all -print`
CONF=$APPALL/environment.conf
source $CONF
QUOTA=${INSTALL_DIR}/apps/rpa_manager/grid-router/quota/${1}.xml
USERS=${INSTALL_DIR}/apps/rpa_manager/grid-router/users.properties

sed 's/\, /\:/' ${USERS} | grep ${1} | while IFS=":" read user password quota;
do
  echo "user='$user' password='$password' quota='$quota'";

  egrep 'host|port' ${QUOTA} | sort | uniq | sed 's/^ *.host name/\host/' | sed 's/\/>//' | tr -d '"' | tr ' ' '=' | awk -F= '{print $2":"$4":"$6}' | while IFS=":" read host port count;
  do
    echo "host='$host' port='$port' count='$count'";
    timeout 3 curl -k -s --data "action=getListNodes" https://$user:$password@$host:$port/grid/admin/WFServlet | python -m json.tool 2>/dev/null | grep 'remoteHost';
    if [[ $? -ne 0 ]]; then
      echo -e "!!! --- HUB $host:$port is unavailable --- !!! \n"
    else
      nod_num=`timeout 2 curl -k -s --data "action=getListNodes" https://$user:$password@$host:$port/grid/admin/WFServlet | python -m json.tool | grep -c 'remoteHost';`
      if [[ ${nod_num} == ${count} ]]; then
        echo -e "All nodes are running on hub ${host} \n"
      else
        echo -e "${nod_num} node(s) are running. Please check other nodes on hub ${host} or adjust quota file and restart rpa_manager service. Should be ${count} node(s) \n"
      fi
    fi
  done
done

Usage example (the first parameter is the name of the file from the quota or directory):

$ ./check_hub.sh users
