> Port Schema Statistics
> The Port schema provides operational statistics that can be used for monitoring and troubleshooting the following products: All
> This schema provides the following types of statistics:

> • | Counter: A counter records incremental data cumulatively and rolls over when the counter limit is reached.

> • | All counter statistics are cumulative and reset only by one of the following methods: roll-over when limit is reached, after a system restart, or after a clear command is performed.

> • | The limit depends upon the data type.

> • | Gauge: A gauge statistic indicates a single value; a snapshot representation of a single point in time within a defined time frame. The gauge changes to a new value with each snapshot though a value may repeat from one period to the next. The limit depends upon the data type.

> • | Information: This type of statistic provides information, often intended to differentiate sets of statistics; for example, a VPN name or IP address. The type of information provided depends upon the data type.

> The data type defines the format of the data for the value provided by the statistic. The following data types are used in statistics for this schema:

> • | Int32/Int64: An integer, either 32-bit or 64-bit:

> • | For statistics with the Int32 data type, the roll-over to zero limit is 4,294,967,295.

> • | For statistics with the Int64 data type, the roll-over to zero limit is 18,446,744,073,709,551,615.

> • | Float: A numeric value that can be represented fractionally; for example, 1.345.

> • | String: A series of ASCII alphanumeric characters in a single grouping, usually pre-configured.

> Important: Unless otherwise indicated, all statistics are counters and all statistics are standards-based.
> Key Variables: Every schema has some variables which are typically referred to as 'key variables'. These key variables provide index markers to identify which object the statistics apply to. For example, in the card schema, the card number (variable %card%) uniquely identifies a card. For an HA service, the keys would be "%vpnname%" plus "%servname%", as the combination uniquely identifies an HA service. So, in a given measurement interval, one row of statistics will be generated per unique key. The schema keys are identified in the Description section of the table.
> Bulk Statistic Variables in the Port-level Schema

> Variables | Description | Data Type
> card | Chassis slot numbers 17 through 48. This is a key variable. Type: Information | Int32
> port | Port number on the card; 0 through 7 for the Ethernet 10/100 Line Card, 0 for the Ethernet 1000 Line Card, 0 through 3 for the four-port Quad Gig-E line card (ST40 only), and 0 through 1 for the SPIO. This is a key variable. Type: Information | Int32
> maxrate | The maximum physical data rate for the port. For example a 10/100 Ethernet port that has negotiated a 10 Mbps rate reports 100,000,000 as the max rate (100 Mbps). Type: Counter | Int64
> rxbytes | The number of bytes received over the port. Type: Counter | Int64
> txbytes | The number of bytes transmitted over the port. Type: Counter | Int64
> ucast_inpackets | The number of unicast packets received over the port. Type: Counter Important: This statistic is not supported for SPIO ports. | Int64
> ucast_outpackets | The number of unicast packets sent over the port. Type: Counter Important: This statistic is not supported for SPIO ports. | Int64
> mcast_inpackets | The number of multicast packets received over the port. Type: Counter Important: This statistic is not supported for SPIO ports. | Int64
> mcast_outpackets | The number of multicast packets sent over the port. Type: Counter Important: This statistic is not supported for SPIO ports. | Int64
> bcast_inpackets | The number of broadcast packets received over the port. Type: Counter Important: This statistic is not supported for SPIO ports. | Int64
> bcast_outpackets | The number of broadcast packets sent over the port. Type: Counter Important: This statistic is not supported for SPIO ports. | Int64
> rxpackets | The number of packets received over the port. Type: Counter | Int64

> txdiscbytes | The number of bytes transmitted over the port that were discarded. Type: Counter | Int64
> txdiscpackets | The number of packets transmitted over the port that were discarded. Type: Counter | Int64
> frag-rcvd | The number of fragments received on this port. Type: Counter | Int64
> pkt-reassembled | The number of packets re-assembled from fragments received on this port. Type: Counter | Int64
> frag-tokernel | The number of fragments received on this port and sent to the kernel. Type: Counter | Int64
> util-rx-curr | The current average port utilization for received data in Mbps. Type: Counter | Int64
> util-tx-curr | The current average port utilization for transmitted data in Mbps. Type: Counter | Int64
> util-rx-5min | The average port utilization for received data over the last five minutes in Mbps. Type: Counter | Int64
