TRANSLATING

+

Introduction

+ +

Send remote commands to the Pegasus cluster through the remote_command command of the Pegasus shell tool, which includes a command name and 0 or more parameters, and can achieve functions such as information collection and configuration modification.

+ +

Performing operations through remote commands has these benefits:

+
    +
  • Direct communication: The command will be sent directly to the target remote process without the need for routing or forwarding.
    • +
  • Quick take effect: commands are usually executed immediately and take effect without waiting for time.
    • +
  • Easy development: No need to introduce new RPC, just register a new command name, parameter parsing method, and callback function.
    • +
+ +

Supported commands

+ +

Pegasus supports different remote commands for different roles (MetaServer, ReplicaServer). +You can query all supported commands through shell tool remote_command help command.

+ +

MetaServer

+ +

Obtain remote commands supported by MetaServer, for example:

+
>>> remote_command -l 127.0.0.1:34601 help
+COMMAND: help
+
+CALL [user-specified] [127.0.0.1:34601] succeed:
+help|h|H|Help - Display help information
+repeat|r|R|Repeat - Execute a command periodically in every interval seconds for the max count time (0 for infinite)
+config-dump - Dump all configurations to a server local path or to stdout
+engine - Get engine internal information, including threadpools and threads and queues in each threadpool
+fd.allow_list - Show the allow list of failure detector
+flush-log - Flush log to stderr or file
+meta.live_percentage - node live percentage threshold for update
+perf-counters - Query perf counters, filtered by OR of POSIX basic regular expressions
+perf-counters-by-postfix - Query perf counters, filtered by OR of postfix strings
+perf-counters-by-prefix - Query perf counters, filtered by OR of prefix strings
+perf-counters-by-substr - Query perf counters, filtered by OR of substrs
+reset-log-start-level - Reset the log start level
+server-info - Query server information
+server-stat - Query selected perf counters
+system.queue - Get queue internal information, including the threadpool each queue belongs to, and the queue name and size
+task-code - Query task code containing any given keywords
+task.queue_max_length - Get the current or set a new max task queue length of a specific thread_pool. It can be set it to INT_MAX which means a big enough value, but it can't be cancelled the delay/reject policy dynamically
+
+
+Succeed count: 1
+Failed count: 0
+
+ +

ReplicaServer

+ +

Obtain remote commands supported by ReplicaServer, for example:

+
>>> remote_command -l 127.0.0.1:34801 help
+COMMAND: help
+
+CALL [user-specified] [127.0.0.1:34801] succeed:
+help|h|H|Help - Display help information
+repeat|r|R|Repeat - Execute a command periodically in every interval seconds for the max count time (0 for infinite)
+config-dump - Dump all configurations to a server local path or to stdout
+engine - Get engine internal information, including threadpools and threads and queues in each threadpool
+flush-log - Flush log to stderr or file
+nfs.max_copy_rate_megabytes_per_disk - The maximum bandwidth (MB/s) of writing data per local disk when copying from remote node, 0 means no limit, should be greater than 'nfs_copy_block_bytes' which is 4194304
+nfs.max_send_rate_megabytes_per_disk - The maximum bandwidth (MB/s) of reading data per local disk when transferring data to remote node, 0 means no limit
+perf-counters - Query perf counters, filtered by OR of POSIX basic regular expressions
+perf-counters-by-postfix - Query perf counters, filtered by OR of postfix strings
+perf-counters-by-prefix - Query perf counters, filtered by OR of prefix strings

+replica.kill_partition - Kill partitions by (all, one app, one partition)
+replica.max-concurrent-bulk-load-downloading-count - The maximum concurrent bulk load downloading replica count
+replica.mem-release-max-reserved-percentage - control tcmalloc max reserved but not-used memory percentage
+replica.query-app-envs - Query app envs on the underlying storage engine by app_id or app_id.partition_id
+replica.query-compact - Query full compact status on the underlying storage engine by app_id or app_id.partition_id
+replica.release-all-reserved-memory - Release tcmalloc all reserved-not-used memory back to operating system
+replica.release-tcmalloc-memory - control if try to release tcmalloc memory
+replica.trigger-checkpoint - Trigger replicas to do checkpoint by app_id or app_id.partition_id
+replica.verbose-client-log - control if print verbose error log when reply read & write request
+replica.verbose-commit-log - control if print verbose log when commit mutation
+reset-log-start-level - Reset the log start level
+server-info - Query server information
+server-stat - Query selected perf counters
+system.queue - Get queue internal information, including the threadpool each queue belongs to, and the queue name and size
+task-code - Query task code containing any given keywords
+task.queue_max_length - Get the current or set a new max task queue length of a specific thread_pool. It can be set it to INT_MAX which means a big enough value, but it can't be cancelled the delay/reject policy dynamically
+

Onebox使用Prometheus 如果使用onebox, 请首先修改配置文件src/server/config.min.ini以开启Prometheus推送. 但不需要改动 prometheus_port. [pegasus.server] perf_counter_sink = prometheus prometheus_port = @PROMETHEUS_PORT@ 由于onebox模式下多个Pegasus服务进程部署在一台机器上，因此各replica、meta、collector的prometheus端口存在冲突问题. 当前我们的解决办法是对每个进程配置单独的prometheus port: collector : 9091 meta: [9092, 9093, 9094…] replica: [9092+{META_COUNT}, 9093+{META_COUNT}, 9094+{META_COUNT}…] 例如一个2 meta, 3 replica, 1 collector的onebox集群, 其端口对应如下: ./run.sh start_onebox -r 3 -m 2 -c meta1: 9092, meta2: 9093 replica1: 9094, replica2: 9095, replica3: 9096 第二步: 安装及运行 Prometheus wget https://github.com/prometheus/prometheus/releases/download/v2.15.2/prometheus-2.15.2.linux-amd64.tar.gz tar xvfz prometheus-2.15.2.linux-amd64.tar.gz cd prometheus-2.15.2.linux-amd64 修改prometheus目录下的prometheus.yml文件，配置模板如下所示： global: scrape_interval: 5s scrape_configs: - job_name: 'pegasus' static_configs: - targets: ['collector_host:9091'] labels: group: collector - targets: ['meta_host1:9091', 'meta_host2:9091', 'meta_host3:9091'] labels: group: meta - targets: ['replica_host1:9091', 'replica_host2:9091', 'replica_host3:9091'] labels: group: replica # # NOTE: Add the following lines if node exporter is deployed. # - targets: # [ # 'node_exporter_host1:9100', # 'node_exporter_host2:9100', # ... # 'node_exporter_hostn:9100', # ] # labels: # group: node_exporter 对于上述通过 ./run.sh start_onebox -r 3 -m 2 -c 启动的onebox集群, 实际配置如下: global: scrape_interval: 5s scrape_configs: - job_name: "pegasus" static_configs: - targets: ["0.0.0.0:9091"] labels: group: collector - targets: ["0.0.0.0:9092", "0.0.0.0:9093"] labels: group: meta - targets: ["0.0.0.0:9094", "0.0.0.0:9095", "0.0.0.0:9096"] labels: group: replica 修改完prometheus.yml之后，启动prometheus: ./prometheus --config.file=prometheus.yml 进入网址 localhost:9090 看到如下界面即表示到这一步为止是成功的。 注: 如果你想要测试Prometheus是否正确配置, 可以检查 http://{prometheus_host}:9090/targets 查看各节点的监控上报状态. 在Expression框内输入需要查找的内容，点击Excute即可在Element中展示查找到的内容，当选择Graph时可以显示该内容一段时间内数值变化情况。 注意 实际运维过程中, 我们通常需要获取一些机器及操作系统的监控指标, 如cpu.busy, disk.iostat等等, 所以在部署Pegasus集群的时候，可以考虑在每一台机器上部署一个node exporter后台实例，具体可参考: Node Exporter Alert Manager 为 Prometheus 报警组件，需单独部署（暂不提供方案，可参照官方文档自行搭建）。通过 Alert Manager，用户可以配置报警策略，接收邮件、短信等报警。 目前我们的prometheus.yml使用的是静态配置的方式（static_configs），其缺点是当动态扩容缩容的时候需要手动去修改该静态配置。当前Prometheus支持多种动态服务发现方式，例如k8s、consul和dns等等，用户也可以根据自己需求去定制实现。详情请参考文档：配置文件说明、实现动态服务发现 配置 Grafana 本小节介绍如何配置 Grafana。 第一步: 安装及运行 Grafana 首先下载grafana二进制包: wget https://dl.grafana.com/oss/release/grafana-6.0.0.linux-amd64.tar.gz //如果报错，可以尝试在后面添加--no-check-certificate tar -zxvf grafana-6.0.0.linux-amd64.tar.gz cd grafana-6.0.0 启动Grafana ./bin/grafana-server web 观察到如下输出，即为启动成功 INFO[07-24|14:36:59] Starting Grafana logger=server version=6.0.0 commit=34a9a62 branch=HEAD compiled=2019-02-25T22:47:26+0800 ... INFO[07-24|14:37:00] HTTP Server Listen logger=http.server address=0.0.0.0:3000 protocol=http subUrl= socket= INFO[07-24|14:37:00] cleanup of expired auth tokens done logger=auth count=2 第二步: 添加 Prometheus 数据源 登录 Grafana 界面。如下图所示: 默认地址：http://localhost:3000 默认账户：admin 默认密码：admin 注意： Change Password 步骤可以选择 Skip。 点击 Grafana 侧边栏菜单 Configuration 中的 Data Source。 点击 Add data source。 指定数据源的相关信息： 在 Name 处，为数据源指定一个名称。 在 Type 处，选择 Prometheus。 在 URL 处，指定 Prometheus 的 IP 地址。 根据需求指定其它字段。 点击 Add 保存新的数据源。 第三步: 导入 Pegasus DashBoard 目前Pegasus拥有一个DashBoard，用于提供一些基本的监控信息。其相应的json文件: Pegasus json文件 下载了json文件后，可以通过import的方式将其导入进去。其步骤如下： 进入grafana，点击左边框的”+”，选择import，进入import页面 点击右上角的”Upload .json File”，然后选择文件。选择之后进入如下页面 然后点击左下角的”import”按钮完成导入，并进入到Pegasus相应的DashBoard，其页面如下所示 从图中可以看出，Pegasus的DashBoard分为两个row: Pegasus-Cluster和Pegasus-Table，分别代表集群级别监控和表级监控。在左上角的cluster_name后输入具体的集群名字，便可以查看该集群相应的各种监控信息。","headline":"Monitoring","mainEntityOfPage":{"@type":"WebPage","@id":"/administration/monitoring"},"url":"/administration/monitoring"}

简介

 
-
Pegasus基于rDSN框架构建，可以利用到rDSN框架的很多有用的功能，远程命令就是其中一个。

-
-
rDSN框架通过RPC对外提供服务，除了开发者注册的用于业务逻辑的RPC服务，还提供了内建的RPC服务RPC_CLI_CLI_CALL，接口定义如下：

-
struct command
-{
-    1:string       cmd;
-    2:list<string> arguments;
-}
-
-service cli
-{
-    string call(1:command c);
-}
-

-
RPC的请求参数为command结构体，指定远程命令的cmd和arguments；RPC的返回结果是string。

-
-
开发者可以注册各种远程命令，对远程命令处理并返回结果。你可以通过shell的remote_command接口向Pegasus的进程发送远程命令，以执行某些操作。

+
通过 Pegasus shell 工具的 remote_command 命令向 Pegasus 集群发送远程命令，命令包含一个命令名和 0 个或多个参数，可以实现如信息收集、配置修改等功能。

 
 
通过远程命令执行操作有这些好处：

 
    
-  
  • 直接。命令直接发给目标进程。
    • 
-  
  • 快速生效。命令一般都是立即执行。
    • 
-  
  • 开发简单。注册和开发过程都很容易。
    • 
+  
  • 直接通信：命令会直接发给远程目标进程，而无需路由或转发。
    • 
+  
  • 快速生效：命令一般都是立即执行并生效，无需等待时间。
    • 
+  
  • 开发简单：无需引入新的 RPC，只需注册新的命令名、参数解析方式及回调函数即可。
    •

如何使用

 
-
通过shell的remote_command子命令，可以向指定的一个或者多个进程发送远程命令。用法：

-
USAGE:  remote_command         [-t all|meta-server|replica-server] [-l ip:port,ip:port...] <command>
-                               [arguments...]
+Succeed count: 1
+Failed count: 0
 

-
其中需要通过-t或者-l来指定目标进程：

-
    
-  
  • -t：只向指定角色的所有进程发送。
    • 
-  
  • -l：只向指定的地址发送，可以通过列表指定多个地址。
    • 
-
