Re: [prometheus-users] implement smtp connection with blackbox exporter

Re: [prometheus-users] implement smtp connection with blackbox exporter

The following works for me with blackbox_exporter 0.21.0 (maybe your first 'expect' regexp needs to be quoted?) modules: smtp_starttls: prober: tcp timeout: 5s tcp: query_response: - expect: "^220 ([^ ]+) ESMTP (.+)$" send: "EHLO prober"

Re: [prometheus-users] implement smtp connection with blackbox exporter

Yes in my code the first expect is quoted. smtp_starttls: prober: tcp timeout: 5s tcp: query_response: - expect: "^220 ([^ ]+) ESMTP (.+)$" - send: "EHLO prober\r" - expect: "^250-STARTTLS" - send: "STARTTLS\r"

Re: [prometheus-users] implement smtp connection with blackbox exporter

Could you first just try copy-pasting the working config I gave you, and see if it gives a different result to yours? I doubt a mail server would take more than 5 seconds to give a banner, but it's possible. Simply doing "telnet x.x.x.x 25" will show you how your mail server behaves. On Monda

[prometheus-users] Metric relabeling replacing char

Hi. Is it possible to replace certain char in label? I have a metric like this: my_metric{label1=“foo-foo-foo”, label2=“foo”} label1 may have values: foo foo-foo foo-foo-foo and so on It isn’t known how many ‘-’ it has. I want to replace all dashes with underscore in label1 value: my_metric{l

[prometheus-users] Re: Metric relabeling replacing char

> I tried using “metric_relabel_configs” with replace mechanism, but it seems not possible to do with that. If the number is bounded, say no more than 4 dashes, then you can just have 4 rewriting rules, each of which rewrites one. Just repeat the rule N times: - source_labels: [label1]

Thank you for answer. I will try this as a workaround solution. I think there couldn't be more than 5 '-'. >If it's your own exporter - then fix the exporter. No it's a cloud exporter >If it's someone else's exporter - then use the labels as they are. it isn't possible because they use label as

Thank you, it works, but with minor fix with your code - source_labels: [ label1 ] target_label: label1 regex: '([[:alnum:]]+)[-_]+([[:alnum:]]+)' replacement: "${1}_${2}" - source_labels: [ label1 ] target_label: label1
