Periodically query all devices for SNMP values to archive in RRD files

Instance Methods

[hide private]

__init__(self, noopts=0)
Create any base performance directories (if necessary), load cached configuration data and clean up any old RRD files (if specified by --checkAgingFiles)

source code

pickleName(self, id)
Return the path to the pickle file for a device

source code

loadConfigs(self)
Read cached configuration values from pickle files at startup.

source code

cleanup(self, fullPath)
Delete an old RRD file

source code

reportOldFile(self, fullPath)
Add an RRD file to the list of files to be removed

source code

remote_updateDeviceList(self, devices)
Gather the list of devices from zenhub, update all devices config in the list of devices, and remove any devices that we know about, but zenhub doesn't know about.

source code

startUpdateConfig(self, driver)
Periodically ask the Zope server for basic configuration data.

source code

updateDeviceList(self, responses, requested)
Update the config for devices

source code

SnmpConnInfo class

updateAgentProxy(self, deviceName, snmpConnInfo)
Create or update proxy

source code

updateSnmpStatus(self, status)
Update the SNMP failure counts from Status database

source code

remote_deleteDevice(self, doomed)
Allows zenhub to delete a device from our configuration

source code

remote_updateDeviceConfig(self, snmpTargets)
Allows zenhub to update our device configuration

source code

updateDeviceConfig(self, configs)
Examine the given device configuration, and if newer update the device as well as its pickle file.

source code

scanCycle(self, *unused)

source code

setUnresponsiveDevices(self, arg)
Remember all the unresponsive devices

source code

readDevices(self, unused=None)
Periodically fetch the performance values from all known devices

source code

reportRate(self, *unused)
Finished reading all the devices, report stats and maybe stop

source code

checkOldFiles(self)
Send an event showing whether we have old files or not

source code

startReadDevice(self, deviceName)
Initiate a request (or several) to read the performance data from a device

source code

badOid(self, deviceName, oid)
Report any bad OIDs (eg to a file log and Zenoss event) and then remove the OID so we dont generate any further errors.

source code

storeValues(self, updates, deviceName)
Decode responses from devices and store the elements in RRD files

source code

storeRRD(self, device, oid, value)
Store a value into an RRD file

source code

connected(self)
Run forever, fetching and storing

source code

buildOptions(self)
Build a list of command-line options

Method Details

[hide private]

init(self, noopts=0)
(Constructor)

source code

Create any base performance directories (if necessary), load cached configuration data and clean up any old RRD files (if specified by --checkAgingFiles)

Overrides: SnmpDaemon.SnmpDaemon.__init__

loadConfigs(self)

source code


Read cached configuration values from pickle files at startup.

NB: We cache in pickles to get a full collect cycle, because
    loading the initial config can take several minutes.

remote_updateDeviceList(self, devices)

source code

Gather the list of devices from zenhub, update all devices config in the list of devices, and remove any devices that we know about, but zenhub doesn't know about.

NB: This is callable from within zenhub.

Overrides: RRDDaemon.RRDDaemon.remote_updateDeviceList

updateAgentProxy(self, deviceName, snmpConnInfo)

source code

Create or update proxy

Parameters:

deviceName (string) - device name known by zenhub
snmpConnInfo (class SnmpConnInfo from Products/ZenHub/services/PerformanceConfig.py) - object information passed from zenhub

Returns: SnmpConnInfo class

connection information from the proxy

updateDeviceConfig(self, configs)

source code

Examine the given device configuration, and if newer update the device as well as its pickle file. If no SNMP proxy created for the device, create one.

storeRRD(self, device, oid, value)

source code

Store a value into an RRD file

Parameters:

device (string) - remote device name
oid (string) - SNMP OID used as our performance metric
value (number) - data to be stored

buildOptions(self)

source code

Build a list of command-line options

Overrides: RRDDaemon.RRDDaemon.buildOptions
