I added the %s at the end of the service_name, but it complains is missing, I think is not getting it on discovery function. Because of that I want an example for try to do it.
The string table I get is like this:
[[‘HUB_WAN1_0’, ‘190.24.132.38’, ‘1’], [‘HUB_LAN_0’, ‘172.20.90.66’, ‘2’], [‘HUB_WAN2_0’, ‘201.234.246.167’, ‘1’]]
Then I convert it to a dictionary with a function like this:
def parse_tunel_vpn(string_table):
print(string_table)
parsed = {}
column_names = [
"nombreTunel",
"ipTunel",
"estadoTunel",
]
for line in string_table:
parsed[line[0]] = {}
for n in range(1, len(column_names)):
parsed[line[0]][column_names[n]] = line[n]
print("Parseada la info")
print(parsed)
return parsed
And discovery fails, it complain name is missing
Discovery method:
def discover_tunel_vpn(section):
for tunel in section:
yield Service(item=tunel)
I made so many changes in my code that sure I broke something, but I couldn’t get it work. I got the metrics from snmp without problem, but I cannot build services.
