NAME

6       pmdamounts - filesystem mounts performance metrics domain agent (PMDA)
7

SYNOPSIS

9       $PCP_PMDAS_DIR/mounts/pmdamounts [-d domain] [-l logfile] [-U username]
10

DESCRIPTION

12       pmdamounts  is  a  simple Performance Metrics Domain Agent (PMDA) which
13       monitors availability of a given set of filesystem mounts.
14
15       The mounts PMDA exports metrics that  reflect  whether  the  configured
16       filesystems  are  mounted  ("up")  or not.  The list of mount points to
17       monitor is specified  via  the  $PCP_PMDAS_DIR/mounts/mounts.conf  file
18       which simply contains one line for each mount point.
19
20       A brief description of the pmdamounts command line options follows:
21
22       -d   It  is absolutely crucial that the performance metrics domain num‐
23            ber specified here is unique  and  consistent.   That  is,  domain
24            should  be  different for every PMDA on the one host, and the same
25            domain number should be used for the same PMDA on all hosts.
26
27       -l   Location of the log file.  By default, a log file named mounts.log
28            is  written in the current directory of pmcd(1) when pmdamounts is
29            started, i.e.  $PCP_LOG_DIR/pmcd.  If the log file cannot be  cre‐
30            ated  or  is not writable, output is written to the standard error
31            instead.
32
33       -U   User account under which to run the agent.   The  default  is  the
34            unprivileged  "pcp"  account  in  current  versions of PCP, but in
35            older versions the superuser account ("root") was used by default.
36

INSTALLATION

38       If you want access to the names, help text and values  for  the  mounts
39       performance metrics, do the following as root:
40
41            # cd $PCP_PMDAS_DIR/mounts
42            # ./Install
43
44       If you want to undo the installation, do the following as root:
45
46            # cd $PCP_PMDAS_DIR/mounts
47            # ./Remove
48
49       pmdamounts  is  launched  by  pmcd(1)  and  should  never  be  executed
50       directly.  The Install and Remove scripts notify pmcd(1) when the agent
51       is installed or removed.

PCP ENVIRONMENT

67       Environment variables with the prefix PCP_ are used to parameterize the
68       file  and  directory names used by PCP.  On each installation, the file
69       /etc/pcp.conf contains the  local  values  for  these  variables.   The
70       $PCP_CONF  variable may be used to specify an alternative configuration
71       file, as described in pcp.conf(5).
