CLIENT-PMCD ERRORS
These errors may occur in the interactions between a PCP client
and pmcd(1) providing real-time performance data.
PM_ERR_NOAGENT
No PMCD agent for domain of request
A request sent to pmcd(1) requires information from an
agent or PMDA that does not exist. Usually this means the
namespace being used by the client application contains
metric names from a previously installed PMDA.
PM_ERR_CONNLIMIT
PMCD connection limit for this host exceeded
The client connection limit for pmcd(1) is controlled by
the optional access controls in $PCP_PMCDCONF_PATH. By
default there is no limit imposed by the PCP code, and
this error would not be seen.
PM_ERR_AGAIN
Try again. Information not currently available
Used to notify a PCP client that the PMDA responsible for
delivering the information is temporarily unavailable.
See also PM_ERR_PMDANOTREADY.
PM_ERR_NOPROFILE
Missing profile - protocol botch
Internal error in the communication between a client
application and pmcd(1) - should not occur.
PM_ERR_NEEDCLIENTCERT
PMCD requires a client certificate Authentication failure.
PM_ERR_PMDAFENCED
PMDA is currently fenced and unable to respond to requests
A privileged user has decided to isolate a PMDA from
pmcd(1) using a pmStore(1) operation on the
pmcd.agent.fenced metric, which means all fetch-level
requests to that PMDA are being blocked.
