one-stop telemetry collector for nightingale

Categraf

Categraf 是一款 All-in-One 的开源的 telemetry 数据采集器，支持指标、日志采集；支持 Tracing 数据的收集；支持物理机、虚拟机、交换机、容器、K8s、多种中间件/数据库的数据采集，支持混合云架构、云原生架构、多云架构。汇聚领域最佳实践，开箱即用。

特点

❇️ 我们推荐你使用快猫星云旗下的 Flashduty 作为 OnCall 值班平台，Flashduty 支持告警聚合、降噪、认领、升级、排班，让告警的触达既高效，又确保告警处理不遗漏、件件有回响。

❇️ 我们推荐你使用 Categraf 作为采集器，搭配 夜莺Nightingale 快速构建统一的可观测体系。

功能

1. 支持指标、日志的数据采集
2. 支持 Tracing 数据的收集
3. 支持 remote_write 写入协议，支持将数据写入 Promethues、M3DB、VictoriaMetrics、InfluxDB
4. 指标数据只采集数值，不采集字符串，标签维持稳态结构
5. 采用 All-in-One 的设计，所有的采集工作用一个 agent 搞定
6. 纯 Go 代码编写，静态编译依赖少，容易分发，易于安装
7. 尽可能落地最佳实践，不需要采集的数据无需采集，针对可能会对时序库造成高基数的问题在采集侧做出处理
8. 常用的采集器，不但提供采集能力，还要整理出监控大盘和告警规则，用户可以直接导入使用

从源代码编译

# export GO111MODULE=on
# export GOPROXY=https://goproxy.cn

go build
tar zcvf categraf.tar.gz categraf conf

Note: 对于mac os x 用户，请使用 gun-tar 工具打包

brew install gnu-tar
gtar zcvf categraf.tar.gz categraf conf

否则会出现以下报错：

F! failed to init config: failed to load configs of dir: ./conf err:toml: line 1: files cannot contain NULL bytes; probably using UTF-16; TOML files must be UTF-8

运行

# test mode: just print metrics to stdout
./categraf --test

# test system and mem plugins
./categraf --test --inputs system:mem

# print usage message
./categraf --help

# run
./categraf

# run with specified config directory
./categraf --configs /path/to/conf-directory

# only enable system and mem plugins
./categraf --inputs system:mem

# use nohup to start categraf
nohup ./categraf &> stdout.log &

部署在K8s

Categraf 可以以 daemonset, deployment 或者 sidecar 的形式运行在K8s中。

edit k8s/daemonset.yaml, replace NSERVER_SERVICE_WITH_PORT with service ip:port of nserver in your cluster, replace CATEGRAF_NAMESPACE with namespace value, then run:

kubectl apply -n monitoring -f k8s/daemonset.yaml # collect metrics, metrics/cadvisor of node
kubectl apply -n monitoring -f k8s/sidecar.yaml # collect service metrics
kubectl apply -n monitoring -f k8s/deployment.yaml #collect apiserver coredns etc

Notice: k8s/sidecar.yaml is a demo, replace mock with your own image of service.

使用Categraf无缝代替Prometheus抓取数据

如何通过categraf 探针读取kube_state_metrics 数据

请问categraf可以采集自定义指标吗？

categraf或者夜莺可以采集自定义指标吗？
将脚本输出的指标输出到nightingale中去，或者nightingale自己单独可以实现嘛？还是说nightingale只能通过采集器实现

配置input.xxx/xxx.toml支持加密明文密码

建议可以支持对明文密码加密

Describe the solution you'd like

Additional context

把statsd的能力内置集成进来

和metrics-agent、logs-agent、traces-agent同级别的存在，可以参考telegraf和datadog-agent这块的代码

希望添加端口网络流量采集功能

希望添加端口流量采集功能:

目前只有部分收费监控系统才有端口流量统计功能呢:

希望categraf能够采集本机上配置的端口信息，并汇总实时统计网络速率

自动采集服务器上前五的进程

您好，我想请问一下这个采集器是否可以自动采集服务器上前五的进程并形成相应的图表

Categraf 能以daemonset的形式部署在k8s中采集集群节点的监控指标吗

如果在k8s集群中，daemosnet部署后，那配置的prometheus中配置的url，会每个categraf的pod都会重复采集一次对应url中的数据吗

把mtail的能力内置集成进来

和metrics-agent、logs-agent、trace-agent同级别的存在，支持从日志中提取metrics，直接转发给后端时序库，省的再去部署mtail了

增加公共DNS监控

What would you like to be added:
增加DNS监控，指定某域名通过某DNS服务器解析，检测DNS解析是否异常
Why is this needed:
互联网大部分企业都是用的公共dns在解析（https://www.ip.cn/dns.html），当公共DNS服务异常时，会影响企业的经营业务，故需要做DNS监控。
Describe the solution you'd like
域名列表用户自己填写；
DNS服务器集成主要DNS地址（https://www.ip.cn/dns.html）
可自定义标签；
可设置超时时间（自身程序的超时设置）

涉及到每个指标都会有这个 label， 建议将 agent_hostname 更改为 instance, 可能符合 Prometheus 生态的命名规范，也更简洁，使用更方便。

len("instance") < len("agent_hostname")

为何不能用input.elasticsearch 对 aws opensearch的监控？

categraf windows oracle指标支持

默认测试的时候出现metrics_agent.go:40: E! input: oracle not supported

上报的指标有没有可能兼容 node exporter

目前很多公司在使用原生的 node exporter 来监控公司的业务服务器，指标的名称、类型、标签可能和目前的 categraf 都是不兼容的，很难平滑的迁移到 categraf 上，可能无法复用之前的 rules 和一些配置（dashboard）。

有没有什么比较好的方式让这批用户比较简单的迁移到 categraf 上？

增加内部DNS监控

What would you like to be added:
增加内部DNS监控

Why is this needed:
企业在内部网络交换时，在一些业务场景中（比如内部请求API域名）需用到内部dns（bind、powerdns）做解析，不需要到外部DNS绕一圈再回来。故需要监测内部dns（bind、powerdns）服务是否正常。

Describe the solution you'd like

Expected behavior

测试redis采集的metrics

Actual behavior

配置万redis.toml,验证是否采集到相关指标，麻烦在多打印点日志，-debug也没啥日志的

将修改的代码推送到自己仓库准备提 PR 的时候，遇到了报错，应和 workflows 的配置有关系。

switch_legacy自定义OID的数值

想请问下目前目前 switch_legacy自定义OID 得出来的数字能更动后 在推去时序数据库.

比如自定义的OID得出来的数值是 700， 并想要把数字 乘于 0.1。 700 x 0.1 = 70。 之后才推去数据库

switch_legacy invalid memory address or nil pointer dereference 报错

categraf 能不能支持设置header

grafana labs旗下的产品 都有个多租户的概念，是以http请求头 X-Scope-OrgID 来实现的。
categraf 能不能支持设置header，用于兼容grafana的多租户模式。
目前不支持的情况下，可以采用在 remote write api 前加一层nginx反向代理，然后根据不同的server_name来proxy_set_header不同的值。

把 rocketmq-exporter 的能力集成到categraf

exporter类的，可以参考categraf MongoDB插件、categraf kafka插件

哈咯，域名监控有些会白屏

前端版本：5.9.0 后端版本：v5.10.3 categraf:v0.2.9
浏览器edge

如下

夜莺全套安装教程

大佬，能不能出一套全的视频教程，现在查到的资料都是虎头蛇尾的，对于小白很不友好啊。如果可以的话全部使用docker来搭建，配置做一些说明就更好了。非常感谢！
