System
| Description: a description of the device. |
| SNMP ID: the object ID of the agent software. |
| Time Running: how long ago the agent started running. |
| Contact Person: the name of the contact person for the device. |
| Machine Name: the device name. |
| Location: the device's physical location. |
| Description: usually an abbreviated name and version of the interface. |
| Type: a description of what kind of network connection the interface is running. Examples of interface types might be Ethernet-csmacd (which is 10 Megabit Ethernet), PPP or Frame Relay. |
| Address: the network's physical address for the interface. |
| Max Speed (Kbps): the maximum speed reported for the interface. |
| Status: indicates whether the interface can actually transmit and receive network data. If the status is down, this usually indicates the interface has not been configured, or, for a Mac OS computer, indicates that network services such as AppleTalk or TCP/IP are not using the interface. |
| Bytes In: a counter of how many bytes of network data have been received by the interface. |
| Bytes Out: a counter of how many bytes of network data have been transmitted by the interface. |
| Errs In: a counter of how many errors occurred when network data was being received by the interface. |
| Errs Out: a counter of how many errors occurred when network data was being transmitted by the interface. |
| Forwarding?: has two values: Gateway, which indicates that this device routes IP data between one or more network interfaces, and Host, which indicates that this device is an IP end-node and does not route IP data. |
| Default TTL: the Time-To-Live value configured for IP, in seconds. This indicates how long IP data can be routed through an IP network before it is considered too old to route anymore. |
| Receives: how many IP data packets this device has received. |
| Input Header Errors: how many received IP packets discarded because of errors in the IP header, such as TTL exceeded or checksum errors. |
| Input Address Errors: how many received IP packets discarded because of errors in the IP addresses found in the packet. |
| Forwarded Datagrams: how many IP packets received that needed to be routed to other IP addresses, that is, packets that were not addressed to this IP device and needed to be forwarded to another IP device. |
| Input Unknown Protocols: how many received IP packets discarded because the device didn't support a particular protocol. This might be the case if a device receives an SNMP request but SNMP is not enabled. |
| Input Discards: how many received IP packets discarded because problems encountered when trying to process them. Reasons for these discards might be because of lack of input receive memory or because the device is too busy to process the data. |
| Input Delivers: how many received IP packets that were actually received without error. |
| Output Requests: how many IP packets that were attempted to be sent via IP. |
| Output Discards: how many IP packets that could not be sent because of problems such as lack of transmit memory. |
| Output No Routes: how many IP packets that could not be sent because no IP route could be found. This might indicate an unavailable remote network or a misconfigured local IP router. |
| Reassembly Timeout: the maximum number of seconds which received IP fragments of data are held waiting for the rest of their fragments. |
| Reassembly Requireds: how many IP packet fragments of data received which need to be reassembled when all fragments are received. |
| Reassembly OKs: how many IP packets received that were reassembled correctly after all fragments are received. |
| Reassembly Failures: how many IP packets received that could not be reassembled, usually because of timeouts waiting for all fragments. |
| Fragment OKs: how many IP packets that need to be fragmented before they can be sent by this device. |
| Fragment Failures: how many IP packets that need to be fragmented but could not be, usually because of protocol errors. |
| Fragments Created: how many IP packets sent that were generated as the result of fragmentation. |
IP-ARP
Displays information contained in the IP Address Resolution Protocol (ARP) table. ARP is used to translate between IP addresses and physical (hardware) addresses. For example, in order to send IP data to an Ethernet device, the device's Ethernet address must be obtained. ARP is the protocol by which an IP node requests an Ethernet address for a given IP address. The IP-ARP table is useful for mapping IP address assignments to their corresponding Ethernet addresses. The IP-ARP table contains several columns:
| If Index: a number assigned to a device's network interface. This interface is used to send IP data for the particular IP address contained in the third column. |
| Physical Address: the hardware address, usually a six-byte Ethernet address, corresponding to the IP address contained in the third column. |
| Network Address: the IP address that is assigned to the hardware (Ethernet) address contained in the second column. |
| Media Type: one of four values indicating the type of IP-to-Hardware address mapping. "Invalid" indicates that the particular mapping is invalid, usually because of a manual configuration option a user has set. "Dynamic" indicates that ARP has been used to generate a mapping, that is, the device has asked other devices on the network if they can supply a hardware (Ethernet) address for a particular IP address. "Static" indicates that a user has manually configured an address mapping for a particular Ethernet address. "Other" indicates some other type of unspecified mapping. |
Printer Stats
| Description: a description of the device, usually containing a model number and type of printer. |
| Printer Status: the current running status of the printer. This can include: Running, the printer is in operation with no error conditions; Warning, the printer has detected an error (low paper, low toner) but is still operational; Testing: the printer is not available because it is in a test state; or Down, the printer is not available for any use. |
| Impressions Count: the total number of pages printed by this printer. This value may be reset by the printer administrator but generally is the total number of pages printed since the printer was manufactured. |
| Toner/Ink Sources: the total number of toner or ink sources. If this is a monochrome printer, there will usually be only one source. If this is a color printer, there will likely be more than one source. For each source, a three line description will be present under the Toner/Ink Sources number: Description (A description of the toner or ink source, usually containing a model number if the source is a cartridge); Type (The type of the source, which can include Toner, Ink, Ribbon, Wax or many others); and Current / Capacity (The current Toner or Ink capacity and maximum capacity. Many printers cannot sense this data so the Current and/or Capacity values may read zero or unknown.) |
| Printer Toner Type: a description of the device, usually containing a model number and type of printer. |
| Printer Toner Cur/Cap: a description of the device, usually containing a model number and type of printer. |
| Paper Sources: the total number of sources of paper available to the printer. For each source, a three line description will be present under the Paper Sources number: Description (usually the name of the paper tray.); Type (includes such information as whether a tray is removable or non-removable, and the type of paper); and Current / Capacity (current paper source capacity and maximum capacity, which may be zero or unknown if the printer cannot report these data.) |
| Printer Paper Descr: a description of the device, usually containing a model number and type of printer. |
| Printer Paper Type: a description of the device, usually containing a model number and type of printer. |
| Printer Paper Cur/Cap: a description of the device, usually containing a model number and type of printer. |
APC UPS Stats
| Battery Health: indicates whether the UPS batteries need replacing. |
| Runtime (Minutes): the UPS battery run time remaining before battery exhaustion. |
| Low Battery Condition: the status of the UPS batteries. A Battery Low value indicates the UPS will be unable to sustain the current load, and its services will be lost if power is not restored. |
| % Capacity: the remaining battery capacity expressed in percent of full capacity. |
| % Load: the current UPS load expressed in percent of rated capacity. |
| Last Self-Test Status: the results of the last UPS diagnostics test performed. |
| Utility Power Status: the current state of the UPS. |
| Model Number: the UPS model name (e.g. 'APC Smart-UPS 600'). |
| Manufacture Date: the date when the UPS was manufactured in mm/dd/yy format. |
| Battery Replaced Date: the date when the UPS system's batteries were last replaced in mm/dd/yy format. |
| Serial Number: an 8-character string identifying the serial number of the UPS internal microprocessor. |
