2021-03-25stats: python vpp_stats rewrite to access stat segment directlyOle Troan1-296/+482
This module implement Python access to the VPP statistics segment. It accesses the data structures directly in shared memory. VPP uses optimistic locking, so data structures may change underneath us while we are reading. Data is copied out and it's important to spend as little time as possible "holding the lock". Counters are stored in VPP as a two dimensional array. Index by thread and index (typically sw_if_index). Simple counters count only packets, Combined counters count packets and octets. Counters can be accessed in either dimension. stat['/if/rx'] - returns 2D lists stat['/if/rx'][0] - returns counters for all interfaces for thread 0 stat['/if/rx'][0][1] - returns counter for interface 1 on thread 0 stat['/if/rx'][0][1]['packets'] - returns the packet counter for interface 1 on thread 0 stat['/if/rx'][:, 1] - returns the counters for interface 1 on all threads stat['/if/rx'][:, 1].packets() - returns the packet counters for interface 1 on all threads stat['/if/rx'][:, 1].sum_packets() - returns the sum of packet counters for interface 1 on all threads stat['/if/rx-miss'][:, 1].sum() - returns the sum of packet counters for interface 1 on all threads for simple counters Type: refactor Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I1fe7f7c7d11378d06be8276db5e1900ecdb8f515 Signed-off-by: Ole Troan <ot@cisco.com>

2020-05-25api: add new stream message conventionOle Troan1-14/+36
Instead of having to wrap dump/detail calls in control ping, send details messages in between a normal reply / request pair. As expressed in the below service statement. Example: service { rpc map_domains_gets returns map_domains_get_reply stream map_domain_details; }; define map_domains_get { u32 client_index; u32 context; u32 cursor; }; define map_domains_get_reply { u32 context; i32 retval; u32 cursor; }; To avoid blocking the main thread for too long, the replies are now sent in client message queue size chunks. The reply message returns VNET_API_ERROR_EAGAIN when there is more to read. The API handler must also include a "cursor" that is used to the next call to the get function. API handler example: REPLY_AND_DETAILS_MACRO (VL_API_MAP_DOMAINS_GET_REPLY, mm->domains, ({ send_domain_details (cursor, rp, mp->context); })); The macro starts from cursor and iterates through the pool until vl_api_process_may_suspend() returns true or the iteration reaches the end of the list. Client Example: cursor = 0 d = [] while True: rv, details = map_domains_get(cursor=cursor) d += details if rv.retval == 0 or rv.retval != -165: break cursor = rv.cursor or the convenience iterator: for x in vpp.details_iter(vpp.api.map_domains_get): pass or list(details_iter(map_domains_get)) Change-Id: Iad9f6b41b0ef886adb584c97708dd91cf552749e Type: feature Signed-off-by: Ole Troan <ot@cisco.com>

2019-09-16api: autogenerate api trace print/endianOle Troan1-2/+2
In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files. In two formats, "custom-dump" and "dump". "dump" gives a human friendly list, and "custom-dump" is meant to give a list of commands that can be fed to VAT. This patch only deals with "dump". Prior to this fix, auto-generation was only done for the basic types. This fix adds support for any type, including lists, and supports pretty-printing of enums, strings, IP addresses, MAC addresses and so on.
