gen_estimator_active - test if estimator is currently in use : basic statistics : rate estimator statistics
Returns true if estimator is active, and false if not.
Definition at line 308 of file gen_estimator.c.
| void gen_kill_estimator | ( | struct gnet_stats_basic_packed * | bstats, |
| struct gnet_stats_rate_est * | rate_est | ||

gen_kill_estimator - remove a rate estimator : basic statistics : rate estimator statistics
Removes the rate estimator specified by &bstats and &rate_est.
Note : Caller should respect an RCU grace period before freeing stats_lock

gen_new_estimator - create a new rate estimator : basic statistics : rate estimator statistics : statistics lock : rate estimator configuration TLV
Creates a new rate estimator with &bstats as source and &rate_est as destination. A new timer with the interval specified in the configuration TLV is created. Upon each interval, the latest statistics will be read from &bstats and the estimated rate will be stored in &rate_est with the statistics lock grabed during this period.
Returns 0 on success or a negative error code.

| ) |
gen_replace_estimator - replace rate estimator configuration : basic statistics : rate estimator statistics : statistics lock : rate estimator configuration TLV
Replaces the configuration of a rate estimator by calling gen_kill_estimator() and gen_new_estimator().
Returns 0 on success or a negative error code.
Definition at line 292 of file gen_estimator.c.
gnet_stats_copy_app - copy application specific statistics into statistics TLV : dumping handle : application specific statistics data : length of data
Appends the application sepecific statistics to the top level TLV created by gnet_stats_start_copy() and remembers the data for XSTATS if the dumping handle is in backward compatibility mode.
Returns 0 on success or -1 with the statistic lock released if the room in the socket buffer was not sufficient.
Definition at line 205 of file gen_stats.c.
| int gnet_stats_copy_basic | ( | struct gnet_dump * | d, |

gnet_stats_copy_basic - copy basic statistics into statistic TLV : dumping handle : basic statistics
Appends the basic statistics to the top level TLV created by gnet_stats_start_copy().
Returns 0 on success or -1 with the statistic lock released if the room in the socket buffer was not sufficient.
Definition at line 112 of file gen_stats.c.

gnet_stats_copy_queue - copy queue statistics into statistics TLV : dumping handle : queue statistics
Appends the queue statistics to the top level TLV created by gnet_stats_start_copy().
Returns 0 on success or -1 with the statistic lock released if the room in the socket buffer was not sufficient.
Definition at line 175 of file gen_stats.c.
| int gnet_stats_copy_rate_est | ( | struct gnet_dump * | d, |

| struct gnet_stats_rate_est * | r | ||
| ) |
gnet_stats_copy_rate_est - copy rate estimator statistics into statistics TLV : dumping handle : basic statistics : rate estimator statistics
Appends the rate estimator statistics to the top level TLV created by gnet_stats_start_copy().
Returns 0 on success or -1 with the statistic lock released if the room in the socket buffer was not sufficient.
Definition at line 144 of file gen_stats.c.
gnet_stats_finish_copy - finish dumping procedure : dumping handle
Corrects the length of the top level TLV to include all TLVs added by gnet_stats_copy_XXX() calls. Adds the backward compatibility TLVs if gnet_stats_start_copy_compat() was used and releases the statistics lock.
Returns 0 on success or -1 with the statistic lock released if the room in the socket buffer was not sufficient.

| int gnet_stats_start_copy | ( | struct sk_buff * | skb, |
| int | type, | ||

| struct gnet_dump * | d | ||

gnet_stats_start_copy_compat - start dumping procedure in compatibility mode : socket buffer to put statistics TLVs into : TLV type for top level statistic TLV : statistics lock : dumping handle
Initializes the dumping handle, grabs the statistic lock and appends an empty TLV header to the socket buffer for use a container for all other statistic TLVS.
Returns 0 on success or -1 if the room in the socket buffer was not sufficient.
Definition at line 93 of file gen_stats.c.

gnet_stats_start_copy_compat - start dumping procedure in compatibility mode : socket buffer to put statistics TLVs into : TLV type for top level statistic TLV : TLV type for backward compatibility struct tc_stats TLV : TLV type for backward compatibility xstats TLV : statistics lock : dumping handle
Initializes the dumping handle, grabs the statistic lock and appends an empty TLV header to the socket buffer for use a container for all other statistic TLVS.
The dumping handle is marked to be in backward compatibility mode telling all gnet_stats_copy_XXX() functions to fill a local copy of struct tc_stats.
Returns 0 on success or -1 if the room in the socket buffer was not sufficient.
