## Proposals

### SNMP Configuration

id: SNMP Metrics
type: snmp
interval: 10
host: 127.0.0.1
port: 161
version: v2c
metrics:
    - oid: 1.3.6.....
      name: if_in_octets
      help: ...
      labels:
          ifindex: 15
    - oid: 1.3.6....
      metric: if_out_octets
      labels:
          ifindex: 15

## Questions

* [ ] RPM: arm64/aarch64?
* [ ] procstat: discriminator? - Relabeling

## Todo

* [ ] Procstat:
* [ ] Описать суммирование pid

## Host id

* [ ] /var/lib/dbus/machine-id
* [ ] /etc/machine-id
* [ ] inodes - ["/bin", "/etc", "/lib", "/root", "/sbin", "/usr", "/var"] st_inode

## Redis

# Errorstats
errorstat_ERR:count=1392
errorstat_EXECABORT:count=1
errorstat_NOGROUP:count=1
errorstat_NOPERM:count=900
errorstat_WRONGTYPE:count=207

# Cluster
cluster_enabled:0

# Keyspace
db0:keys=437609,expires=956,avg_ttl=33062274872749

## Relabeling improvements

* [ ] VictoriaMetrics extensions: https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/app/vmagent/README.md#relabeling
* [ ] replacement: Arbitrary labels via `{{name}}`
* [ ] if - thinkig
* [ ] regex as list- thinking

## Discussion

### Marketing and positioning
* [ ] Marketing:
* [ ] Positioning and comparison: telegraf, node_exporter, Grafana Agent
* [ ] Build internal competitor's list
* [ ] Comparison criteria

### Usage

* [ ] Grafana dashboards on a market
* [ ] ansible role

### R&D

* [ ] socket2::MaybeUninitSlice

### TODO

* [ ] regex 1.9
