список модулей Kubernetes для сканирования на наличие запущенных служб PCP (list Kubernetes pods to scan for running PCP services)
Имя (Name)
pcp-kube-pods
- list Kubernetes pods to scan for running PCP
services
Синопсис (Synopsis)
$PCP_BINADM_DIR/discover/pcp-kube-pods
Описание (Description)
pcp-kube-pods
uses kubectl
(1) to provide a list of IP addresses
for PODs running in a local Kubenetes cluster, that may be
running PCP services like pmcd(1) and pmproxy(1).
It is used by the pmfind(1) command and the pmDiscoverServices(3)
API as a ``shell'' command.
The script invokes the kubectl get pod
command line (see
kubectl-get
(1)) to discover IP addresses for pods. The
.status.podIP
output field is extracted from the Kubernetes pod
object(s). Additional options can be specified via configuration
file, such as -l service=database to restrict the results using
Kubernetes pod labels. The default configuration file is
$PCP_SYSCONF_DIR/discover/pcp-kube-pods.conf
.
If no local kubectl
command is found, nothing is reported and an
exit code indicating success is returned.
Диагностика (Diagnostic)
All diagnostics produced are provided by the kubectl
command.
The kubectl
exit status is propogated unchanged.

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