Enjoyed speaking on IT infrastructure monitoring and automation at the Zabbix Benelux Conference. Had a great time attending all the technical and inspirational sessions 🙏

@sputniki @etherealmind @rajeshkumarbin Having the same experience with Alcatel-Lucent Enterprise. All stacks in access en 0% problems with it.

@ecbanks @etherealmind @ntdvps @packetpushers You should add 301 redirects to pass seo page rank to the new taxonomy URL’s.

We started to receive questions from customers regarding this CVE and on the surface, it sounded quite scary.
Patches done to almost every SSH server out there, but no mention of Network OSes.
So I decided to help researchers @TrueSkrillor @lambdafu and @JoergSchwenk by assessing which Network Operating Systems are vulnerable

[Keith Miller @packetologist]

Has someone ever told you that the Wi-Fi is slow or not working properly and all they sent you as evidence was a speed test result? Frustrating isn't it? Too many variables exist to strictly rely on them and I try to explain why in this blog post.

Ansible Networking, You're doing it wrong.

Boost your network playbook efficiency in under a minute:

🎛️ Leverage ansible_network_os for seamless portability.
📁 Switch tasks based on file names, no more conditionals!
🚫 Handle unsupported OS gracefully with with_first_found.

@ntdvps @aninchat @saparikh78 @ALUEnterprise 👀

[Jef Vantongerloo @jefVantongerloo]

Extended the Ansible backup task to email on device configuration changes.

A good way to track and get notified on (unintended) changes if your infrastructure is still transitioning to intent-based networking.

@rickjdon Netbox, Python, Ansible, …

[Jef Vantongerloo @jefVantongerloo]

@ntdvps Same happened to me twice recently. Had to recover from install medium or revert to older kernel.

[Jef Vantongerloo @jefVantongerloo]

@mythryll Done the same POC a while ago.
Really powerful tools 💪

[Jef Vantongerloo @jefVantongerloo]

Experimenting with Docker #Loki setup. Collect and push #MikroTik switch logs to Loki, displayed by Grafana. Really powerful for collecting logs and alerting.

MikroTik remote output -> syslog-ng -> promtail -> Loki <- Grafana

Next up configuring labels for easy filtering 🔥

@rickjdon TextFSM parser or sometimes the Ansible native parser.

[Jef Vantongerloo @jefVantongerloo]

Trigger Ansible tasks on Zabbix alert. Can’t wait to start defining use-cases for this one 🔥

[Zabbix Team @zabbix]

Zabbix 6.4.2 and 6.0.17 are out now and come pre-packaged with the new Event-driven @ansible webhook!

The webhook can be used to send #Zabbix alerts to Event-Driven Ansible and automatically resolve detected problems.

Re-launching my personal blog about Web Development with Python and Flask! Blog posts (including from @testdrivenio ) and over 50 Flask Tips are posted with more Python/Flask content to come!

Ansible just got smarter with event-driven automation.

Here are FIVE different ways to make your IT work:

* faster
* simpler
* more effective

🧵A thread

[Jef Vantongerloo @jefVantongerloo]

As requested, the logic for an Ansible network device reboot. Regardless how long the reboot takes, Ansible will wait for the connection to come up again:

- reboot with interactive prompt
- reset active connection
- wait for connection

#networkautomation #ansible

[Jef Vantongerloo @jefVantongerloo]

@ShvZFR If you are looking for a device reboot logic, here is how: - copy firmware files with `net_put`
- reboot CLI commands with `cli_command`
- reset active connection
- wait for connection

[Jef Vantongerloo @jefVantongerloo]

Made an Ansible role to automatically upgrade Alcatel-Lucent Enterprise Omniswitch firmware. Integrated some additional checks and maintenance commands.

The hardest part was figuring out how to wait for a device reboot 😀 #networkautomation #ansible #AlcatelLucentEnterprise

[Jef Vantongerloo @jefVantongerloo]

@DejanTep I think it will be available afterwards. I will post a link here if it gets published by Zabbix.

Meanwhile, you can already find the demo files at the following repository to get started :)
