10
12 pmdaroomtemp is a Performance Metrics Domain Agent (PMDA) which exports
13 the temperature from one or more sensors built using the DS2480 and
14 DS1280 chipsets and MicroLAN technology from Dallas Semiconductor Cor‐
15 poration.
16
17 The roomtemp PMDA exports metrics that reflect the temperatures from
18 one or more of these devices, in both degrees Celcius and Fahrenheit.
19 Each metric has one instance for each temperature sensor device. The
20 external instance identifiers are the serial numbers (in hex) of the
21 DS1280 chips discovered when the MicroLAN was probed.
22
23 A brief description of the pmdaroomtemp command line options follows:
24
25 -d It is absolutely crucial that the performance metrics domain num‐
26 ber specified here is unique and consistent. That is, domain
27 should be different for every PMDA on the one host, and the same
28 domain number should be used for the same PMDA on all hosts.
29
30 -l Location of the log file. By default, a log file named
31 roomtemp.log is written in the current directory of pmcd(1) when
32 pmdaroomtemp is started, i.e. $PCP_LOG_DIR/pmcd. If the log file
33 cannot be created or is not writable, output is written to the
34 standard error instead.
35
37 If you want access to the names, help text and values for the roomtemp
38 performance metrics, do the following as root:
39
40 # cd $PCP_PMDAS_DIR/roomtemp
41 # ./Install
42
43 If you want to undo the installation, do the following as root:
44
45 # cd $PCP_PMDAS_DIR/roomtemp
46 # ./Remove
47
48 pmdaroomtemp is launched by pmcd(1) and should never be executed
49 directly. The Install and Remove scripts notify pmcd(1) when the agent
50 is installed or removed.

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