List of devices in a group; this is the default view when you click on a group name.
Name - click on the name of the device to view the sub devices contained in it
SNMP Options
View Interface Cache - views a list of cached interfaces (interfaces and values that NetMRG knows about)
Recache Interfaces - recache the interface list (to get new ifAliases or new interfaces, for example)
View Disk Cache - views a list of cached disks (disks and their values that NetMRG knows about)
Recache Disks - recache the list of disks (to get new disks or paths, for example)
Add - add a new device or an existing device to this group
View - views graphs assocated with this device and allows you to edit what graphs are associated with the device
Edit - edits parameters of a device
Delete - deletes the device all sub-devices, monitors, etc underneath it
Create a new device - creates a new device in the current group
Add an existing device to this group - puts a link to an existing device in this group (does not copy it, just refers to it; they are the same device
Device - Name of the device to add to this group
Edit info about a device
General
Name - Name of a device; commonly the hostname
IP or Hostname - IP address of the device, or hostname (must be resolvable by the monitoring box)
Device Type - Type of device (currently not used)
Disabled - Don't gather data for this device
SNMP
SNMP Support - The version of SNMP to use when querying this device, if any.
SNMP Read Community - The SNMP community string to use when querying this device.
Recaching Method - Methods used by the gatherer for determining if its SNMP cache is stale.
Never refresh cache - The gatherer will never automatically refresh the cache. The cache must be refreshed manually when changes occur.
Refresh on SNMP agent restart - The gatherer will refresh the cache if the SNMP agent uptime goes backwards, or if the device has become reachable again after a period of unreachability. This option is useful for devices that change interface counts too often, such as a router serving DSL sessions.
Refresh on interface count change - The gatherer will refresh the cache if the "ifNumber" value has changed since the last gathering. This typically happens when cards are added to or removed from a router, or when PPP sessions go up or down. (Also includes the above.)
Refresh on interface count mismatch - The gatherer will refresh the cache when the number of items in the interface cache do not match the "ifNumber" on a device. This can prevent problems when devices are in the process of booting. This is the preferred option for most devices. (Also includes the above.)
Always refresh cache - Always refresh the cache on each gather. This is useful for devices that are always changing, when you care about the changes.
Advanced SNMP Options
SNMP UDP Port - UDP port to direct SNMP queries to (default is 161).
SNMP Timeout (microseconds) - Number of microseconds to wait for a response to a query before retrying (default is 1000000 or 1 second). An exponential backoff is used after each failed query; this is the initial delay.
SNMP Retries - Number of times to query the device before giving up (default is 3).
List of cached values for a device
List of Interfaces NetMRG knows about
Index - SNMP ifIndex
Status - SNMP ifAdminStatus/ifOperStatus
Name - SNMP ifName
Description - SNMP ifDescr
Alias - SNMP ifAlias (commonly the 'description' field on routers and switches)
IP Address - IP address of this interface
MAC Address - MAC address of this interface
View - View the graph for this interface (if monitored)
Monitors - View the monitors for this interface (if monitored)
Monitor/Graph - Choose to graph this interface (adds an interface subdevice based on ifDescr, adds monitors for ifInOctets, ifOutOctets, and ifInErrors for the subdevice, and assocates a graph with the device)
List of Disks NetMRG knows about
Index - SNMP dskIndex
Device - SNMP dskDevice
Path - SNMP dskPath
View - View the graph for this disk (if monitored)
Monitors - View the monitors for this disk (if monitored)
Monitor/Graph - Choose to graph this disk (adds a disk subdevice based on dskPath, adds monitors for KB Used and KB Available for the subdevice, and assocates a graph with the device)
