Python exception error

[sheevaeva]

Hello I'm in the process of configuring ping exporter and the issue i'm facing is the metric values are not populated on Prometheus (metrics are available). If I access http://IP:8085/probe?prot=4&target=target_ip in the browser i see the values as below:

ping_avg 21.0 ping_max 21.9 ping_min 20.6 ping_loss 0

Prometheus config looks like this '''

• job_name: 'ping-exporter' scrape_interval: 60s metrics_path: /probe params: prot: ['4'] static_configs: - targets: - target_ip relabel_configs: - source_labels: [address] target_label: __param_target - source_labels: [__param_target] target_label: instance - target_label: address replacement: Prom_IP:8085

''' As i run the exporter I see below exception :

2019-09-21 09:44:29,097 root INFO /usr/bin/fping -4 -b 56 -i 1 -p 500 -q -c 10 Target_ip client_ip - - [21/Sep/2019 09:44:33] "GET /probe?prot=4&target=target_ip HTTP/1.1" 200 -

Exception happened during processing of request from ('Prom_IP', 64464) Traceback (most recent call last): File "/usr/lib/python2.7/SocketServer.py", line 596, in process_request_thread self.finish_request(request, client_address) File "/usr/lib/python2.7/SocketServer.py", line 331, in finish_request self.RequestHandlerClass(request, client_address, self) File "/usr/lib/python2.7/SocketServer.py", line 652, in init self.handle() File "/usr/lib/python2.7/BaseHTTPServer.py", line 340, in handle self.handle_one_request() File "/usr/lib/python2.7/BaseHTTPServer.py", line 328, in handle_one_request method() File "/opt/ping-exporter.py", line 58, in do_GET address = value['target'][0] KeyError: 'target'

Would like to know why are the values not populating on Prometheus metrics. Kindly help!

Thanks

The python exception happens everytime the exporter is queried without target query-param. If you call it from a browser the brower usually tries to get a favicon from the webserver. The exception should not occur when scraping with curl (or from prometheus) - it is just an annoying error that fills up the log.
