# Monitor status of Cisco BGP Peer (IPv4 and IPv6)
#
# 24.05.2018: changed counters to 1/s
# 25.05.2018: a lot of code cleanup
# packet name changed from cisco_bgp to cisco_bgp_peer
# added support of more then one address family per peer
# (changed item from remoteip to remoteip+familyname, rewrite of parer, inventory and check function)
# 27.05.2018: changed scan function from '.1.3.6.1.4.1.9.9.187.1.2.7.1.3.* to sysdecr contains cisco
# 28.05.2018: changed wato, added peer alias, state if not found, infotext values
# 29.05.2018: fixed longoutpout (removed not configured)
# 02.11.2018: modified scanfunction (from "find 'cisco' =-1" to "'cisco' in OID"
# 02.18.2019: added fix for empty values ("" instead of "0") sugested by Laurent Barbier (lbarbier[at]arkane-studios[dot]com)
# 24.02.2020: added workaround for missing cbgpPeer2AddrFamily (example L2VPN EVPN peers, Fix for jonale82[at]gmail[dot]com)
# 02.03.2020: changed handling of perfdata, add only data the are really there (not None, instead of setting them to 0)
# 04.06.2020: code cleanup --> changed isdigit test to try/except loop, changed peer.get test to try/except loop
