NAME

6       ocf_heartbeat_varnish - Manage a Varnish instance
7

SYNOPSIS

9       varnish [start | stop | status | monitor | meta-data | validate-all]
10

DESCRIPTION

12       The Varnish Resource Agent can manage several varnishd instances
13       throughout the cluster. It does so by creating a unique PID file and
14       requires a unique listen address and name for each instance.
15

SUPPORTED PARAMETERS

17       config
18           The VCL configuration file that Varnish should manage, for example
19           "/etc/varnish/default.vcl".
20
21           (unique, required, string, no default)
22
23       name
24           Override the name of the instance that should be given to Varnish
25           (defaults to the resource identifier).

28
29       pid
30           Write the process's PID to the specified file. The default will
31           include the specified name, i.e.:
32           "/var/run/varnish_production.pid". Unlike what this help message
33           shows, it is most likely not necessary to change this parameter.
