- __init__(this,
logger)
- # ProcInfo constructor
- addJobToMonitor(this,
pid, workDir)
- # Call this to add another PID to be monitored
- countOpenFD(this,
pid)
- # count the number of open files for the given pid
- countProcesses(this)
- # read the number of processes currently running on the system
- getChildren(this,
parent)
- # internal function that gets the full list of children (pids) for a process (pid)
- getFilteredData(this,
dataHash, paramsList)
- # Return a hash containing (param,value) pairs with existing values from the requested ones
- getJobData(this,
pid, params)
- # Return a filtered hash containing the job-related parameters and values
- getSystemData(this,
params)
- # Return a filtered hash containting the system-related parameters and values
- parsePSTime(this,
my_time)
- # internal function that parses a time formatted like "days-hours:min:sec" and returns the corresponding
# number of seconds.
- readGenericInfo(this)
- # reads the IP, hostname, cpu_MHz, uptime
- readJobDiskUsage(this,
pid)
- # if there is an work directory defined, then compute the used space in that directory
# and the free disk space on the partition to which that directory belongs
# sizes are given in MB
- readJobInfo(this,
pid)
- # read information about this the JOB_PID process
# memory sizes are given in KB
- readLoadAvg(this)
- # read system load average
- readMemInfo(this)
- # sizes are reported in MB (except _usage that is in percent).
- readNetworkInfo(this)
- # read network information like transfered kBps and nr. of errors on each interface
- readNetStat(this)
- # run nestat and collect sockets info (tcp, udp, unix) and connection states for tcp sockets from netstat
- readStat(this)
- # this has to be run twice (with the $lastUpdateTime updated) to get some useful results
# the information about pages_in/out and swap_in/out isn't available for 2.6 kernels (yet)
- removeJobToMonitor(this,
pid)
- # Call this to stop monitoring a PID
- update(this)
- # This should be called from time to time to update the monitored data,
# but not more often than once a second because of the resolution of time()
