# check_pgbackrest
## Introduction
This `Vagrantfile` is bootstrapping 3 possible test cases:
### 1. pgBackRest configured to backup and archive on a CIFS mount
* `icinga-srv` executes check_pgbackrest by ssh with Icinga 2;
* `pgsql-srv` hosting a pgsql cluster with pgBackRest installed;
* `backup-srv` hosting the CIFS share.
Backups and archiving are done locally on `pgsql-srv` on the CIFS mount point.
### 2. pgBackRest configured to backup and archive remotely
* `icinga-srv` executes check_pgbackrest by ssh with Icinga 2;
* `pgsql-srv` hosting a pgsql cluster with pgBackRest installed;
* `backup-srv` hosting the pgBackRest backups and archives.
Backups of `pgsql-srv` are taken from `backup-srv`.
Archives are pushed from `pgsql-srv` to `backup-srv`.
Checks (retention and archives) are done both locally (on `backup-srv`) and
remotely (on `pgsql-srv`). Checks are performed from `icinga-srv` by ssh.
pgBackRest backups are use to build a Streaming Replication with `backup-srv`
as standby server.
### 3. pgBackRest configured to backup and archive to a MinIO S3 bucket
* `icinga-srv` executes check_pgbackrest by ssh with Icinga 2;
* `pgsql-srv` hosting a pgsql cluster with pgBackRest installed;
* `backup-srv` hosting the MinIO server.
## Testing
The easiest way to start testing is with the included `Makefile`.
### Test case 1
_Build_:
```bash
cd test
make s1
```
Expected make time: 7 min.
_Check the results of a manual execution of check_pgbackrest_:
```bash
vagrant ssh pgsql-srv -c "sudo /check_pgbackrest/test/regress/test-s1.bash"
```
Expected run time: 30 sec.
_To simulate some activity with pgBackRest_:
```bash
vagrant ssh pgsql-srv -c "sudo /check_pgbackrest/test/regress/simulate-activity-local.bash"
```
Modify `SCALE` factor or `ACTIVITY_TIME` in this script to simulate more activity.
### Test case 2
_Build_:
```bash
cd test
make s2
```
Expected make time: 6 min.
_Check the results of a manual execution of check_pgbackrest_:
```bash
vagrant ssh pgsql-srv -c "sudo /check_pgbackrest/test/regress/test-s2-from-primary.bash"
```
Expected run time: 50 sec.
### Test case 3
_Build_:
```bash
cd test
make s3
```
Expected make time: 8 min. (depends on MinIO download time)
_Check the results of a manual execution of check_pgbackrest_:
```bash
vagrant ssh pgsql-srv -c "sudo /check_pgbackrest/test/regress/test-s3.bash"
```
Expected run time: 40 sec.
_To simulate some activity with pgBackRest_:
```bash
vagrant ssh pgsql-srv -c "sudo /check_pgbackrest/test/regress/simulate-activity-local.bash"
```
Modify `SCALE` factor or `ACTIVITY_TIME` in this script to simulate more activity.
### Icinga 2 connectivity
_Check the results of _check_pgbackrest_ launched by Icinga 2:
```bash
vagrant ssh icinga-srv -c "sudo icingacli monitoring list services --service=pgbackrest* --verbose"
```
_Navigate to Icinga Web 2_:
Get the IP address of `icinga-srv` with:
```bash
vagrant ssh icinga-srv -c "ip addr show eth0"
```
And then go to `http://IP/icingaweb2`. Credentials are `icingaweb / icingaweb`.
### Clean up
Don't forget to clean the VM's after the tests:
```bash
make clean
```
### Generate expected regress test results
Edit the `test-*.bash` scripts and set `GENERATE_EXPECTED` to true. Run it.
Currently, expected tests results are the same for test cases 1 and 2.
## Build pgBackRest GitHub master version
To perform tests using the latest GitHub version, execute the following script
on each server where pgBackRest is installed :
```bash
vagrant ssh pgsql-srv -c "sudo /check_pgbackrest/test/regress/pgbackrest_build.bash"
```
### Extended activity
```bash
Usage: simulate-extended-activity.bash [-s <scale>] [-a <activity_time>] [-p <local|remote>]
vagrant ssh pgsql-srv -c "sudo /check_pgbackrest/test/regress/simulate-extended-activity.bash -s 10 -a 10 -p local"
```
## Tips
Find all existing VM created by vagrant on your system:
```bash
vagrant global-status
```
Shutdown all VM:
```bash
vagrant halt
```
Restart the halted cluster:
```bash
vagrant up
```
