How should I specify more auths in one `generator.yml` file? Actually on **0.23.0-rc.1** I have `generator.yml` like: ```auto auths: auth_cisco: version: 2 community: BLABLA auth_checkpoint: version: 2 community: BLABLA2 auth_viptela: version: 3 username: BLABLA3 security_level: authPriv password: BLABLA4 auth_protocol: SHA priv_protocol: AES priv_password: BLABLA5 context_name: context modules: ... ``` When I generate `snmp.yml` and copy it to snmp\_exporter and run it, when I execute snmp\_exporter in web page, it shows me message: **Unknown auth ‘public\_v2’** So it means, that I have to use just specific names for `auths` block? Like `public_v1`, `public_v2` and `public_v3`? I’ve tried to manage it by myself, and it looks, that more auths method is not possible. Especially v2 and v3 together. **TEST1:** ```auto auths: public_v2: version: 2 community: BLABLA1 public_v2: version: 2 community: BLABLA2 ``` result: not possible **Two same public\_v2 names** **TEST2:** v2 + v3 ```auto auths: public_v2: version: 2 community: BLABLA2 public_v3: version: 3 username: BLABLA3 security_level: authPriv password: BLABLA4 auth_protocol: SHA priv_protocol: AES priv_password: BLABLA5 context_name: context ``` result: snmp\_exporter uses **auth=public\_v2** why?? `caller=collector.go:218 level=debug auth=public_v2 module=viptela_mib target=10.128.XX.XXX msg="Walking subtree" oid=1.3.6.1.4.1.41916.3` ---

> **Unknown auth ‘public\_v2’** This means you did not specify any auth method. You forgot to include one of the auths you specified like `auth_checkpoint`. ---

You mean in `modules`? ---

@SuperQ - ok I’ve tried in generetaro from 0.23.rc-1 this: ```auto auths: auth_cisco: version: 2 community: BLA auth_checkpoint: version: 2 community: BLA auth_brocade: version: 2 community: Bla auth_viptela: version: 3 username: BLE security_level: authPriv password: BLA auth_protocol: SHA priv_protocol: AES priv_password: BLA # context_name: contenxt modules: cisco_mib: auth: name: auth_cisco walk: .... ``` but error appears of course… ```auto ts=2023-08-15T07:19:56.001Z caller=main.go:122 level=warn msg="NetSNMP reported parse error(s)" errors=9 ts=2023-08-15T07:19:56.202Z caller=main.go:132 level=error msg="Error generating config netsnmp" err="error parsing yml config: yaml: unmarshal errors:\n line 24: field auth not found in type main.plain" ``` How can I specify which auth method is used for each module please. ---

OMG… how stupid am I 🙂 I was focused to fill up `auths` in `generator.yml` and `snmp.yml` somehow… that I missed that it should be added to `prometheus.yml` file ☹ It has to be filled in this section as it is written in manual ([https://github.com/prometheus/snmp\_exporter/blob/main/README.md#prometheus-configuration](https://github.com/prometheus/snmp_exporter/blob/main/README.md#prometheus-configuration)) ```auto - job_name: 'snmp' static_configs: - targets: - 192.168.1.2 # SNMP device. - switch.local # SNMP device. - tcp://192.168.1.3:1161 # SNMP device using TCP transport and custom port. metrics_path: /snmp params: auth: [public_v2] module: [if_mib] ``` ---

Yes, that’s it. If you wanted to use another auth entry like `auth_brocade` you would just change the group like this: > [@tom.i](#): > > ```auto > - job_name: 'snmp-brocade' > static_configs: > - targets: > - 192.168.1.2 # Brocade SNMP device. > metrics_path: /snmp > params: > auth: [auth_brocade] > module: [if_mib] > > ``` ---

so that mean prometheus can’t pull snmp-exporter with multi-communities in 1 time right ? ---

I also have this issue! I have multiple vendors and multiple authenticates! auths: dell\_snmpv3 Lenovo\_snmpv3 APC\_snmpv3 modules: dell lenovo APC ---

Yes, you can add as many communities / authenticates as you want 😉 ---

Hi tom.i I’m trying to set this up myself, having gone from monitoring one type of device with a community string configured through the snmp.yml to needing to monitor multiple types of device with different community strigns, and am struggling. Can you share a screen shot of how you’ve added this to and gotten it working from your prometheus.yml file? Cheers Paul ---

Got there this morning, think I needed to look at it with fresh eyes!
