Pingsheet

Introduction

Pingsheet is a cloud based latency and packet loss monitoring platform built on
top of Google Sheets.

A Google Sheet is used to configure a swarm of hosts with targets they should
ping, the hosts run the pings and add the results back into the Google Sheet.

As the data is in Google Sheets it makes it very simple and flexible to create
dashboards using conditional formatting and charts.

Due to limitations on how big a sheet can become this is best suited for short
term data.

Usage

1. Start by creating the required Google Sheets API credentials
2. Then import the template sheet into Google Sheets
3. Configure your hosts, settings and targets in the Google Sheet
4. Download and install the latest executable for your host platform
   • Mac OS

     wget https://github.com/adamkirchberger/pingsheet/releases/latest/download/pingsheet_Darwin_x86_64.tar.gz && \
     tar xvzf pingsheet_Darwin_x86_64.tar.gz pingsheet && \
     xattr -dr com.apple.quarantine pingsheet && \
     mv pingsheet /usr/local/sbin/

   • Linux

     wget https://github.com/adamkirchberger/pingsheet/releases/latest/download/pingsheet_Linux_x86_64.tar.gz && \
     tar xvzf pingsheet_Linux_x86_64.tar.gz pingsheet && \
     mv pingsheet /usr/local/sbin/

5. Run the tool

   pingsheet --credentials {{path-to-credentials}} --sheet {{sheet-ID}} --hostname {{hostname}} --secret {{secret}}

6. The tool will check for a config in the Google Sheet and run ping tests to the targets

7. The tool will automatically create a worksheet to add all the results

   • New results are added to the bottom as rows
   • The 1st row contains the headers
   • The 2nd row includes a formula to show the last metric

Setup

Create Google Credentials

Install

Mac OS

curl https://sdk.cloud.google.com | bash
exec -l $SHELL

Other OS’s

• Follow the steps in https://cloud.google.com/storage/docs/gsutil_install

Instructions

1. Run login init command

   gcloud init

2. This will open a browser make sure to grant access

3. Create a new project

4. Enable Google Sheets API

   gcloud services enable sheets.googleapis.com

5. Create new service account

   gcloud iam service-accounts create pingsheet --display-name=pingsheet
   Created service account [pingsheet].

6. Find the name of the newly created service account

   gcloud iam service-accounts list
   NAME        EMAIL                                          DISABLED
   pingsheet   pingsheet@testproj.iam.gserviceaccount.com  False

7. Create JSON key file using email from created service-account

   gcloud iam service-accounts keys create credentials.json --iam-account=pingsheet@testproj.iam.gserviceaccount.com

Google Sheet

1. Create a Google Sheet from the template in the repo pingsheet_template.xls

2. Share the sheet with the email address from the key generated above
   eg: pingsheet@testproj.iam.gserviceaccount.com

3. Ensure that the user has Editor/Write permissions

Config

You should now have a Google Sheet created from the template and credentials
ready to use with sheet editing permissions.

1. Add all the hosts where the pingsheet tool will run and initiate pings.

   • Add a hostname to the HOSTNAME column
   • Add a secret to the SECRET column

2. Configure the INTERVAL, COUNT and MAXROWS

   • INTERVAL: The amount of seconds between ping tests (All targets are run in parallel)
   • COUNT: The amount of pings to send to each target
   • MAXROWS: The maximum number of results to keep

3. Configure ping targets for each host

   • Add as many columns as necessary starting at TARGET_1, TARGET_2, etc…

FAQ

How often does the tool check for new targets?

The tool checks for new targets every 5 minutes. Any targets that have been removed will also be updated and no longer pinged.

What happens if the host running the tool loses Internet access?

The tool does not keep any results locally so any tests performed during this
time will be lost, however when the tool encounters an issue it will keep
retrying every 60 seconds.

Are there any plans to test latency to TCP ports?

This is something that could be implemented in the future.
