+In this directory you find contributed scripts
+
+in externalscripts: cvpoller-zabbix/vpoller-zabbix both scripts have additional checks
+to ensure that when a vcenter server is down or the vpoller-proxy is down the items
+get the status: "Not Supported"
+
+This solves the issue of all zabbix agents become unreachable due to vcenter down and the
+zabbix queue is getting full.
+
+Requirements for these scripts is that a recent version of `curl` is installed.
