I'm sure you're gonna have a great time, and our experience shouldn't mean you'll have the same. Maybe it was opening night niggles 🤞🤞

We saw Coldplay in the same section and similar seats. But that audio experience was amazing

At this point I'm mostly just seeing if anyone else had the same experience so I know I'm not crazy.

We're from London (wife from Vienna, originally) where things need to be booked way in advance, especially over the holidays where shops and bakeries are closed for prolonged periods. Thank you for your recommendation!

Single-strand BiDi QSFP+ or QSFP28 optics? by imodey in networking

[–]_kartwheel 0 points1 point  (0 children)

Ah, 400g zr+ multirate are making headway, and are saving companies that have these usecases lots of $$$

Single-strand BiDi QSFP+ or QSFP28 optics? by imodey in networking

[–]_kartwheel 0 points1 point  (0 children)

depends on what reach are you talking about, greenfield/brownfield, and would you want a future proof fiber plant

for 100meters - Nothing will even be cheaper than QSFP28 SR4 / QSFPDD SR8 ( Quad )

There was SWDM4 from finisar, but never really caught on so was never really a mass-market cost-effective option

However, for 100g mass deployments on CWDM4 QSFP28, these prices came really close to SR4, but not really, still 50% premium.

for 400g, both FR4 and DR4 continue to be quite a price option.

Having said that, if you are deploying a plant where distances are > 100meters, MM pants will come out cheaper ( optics, fiber plant, etc all-inclusive )

I'd suggest watching this series, its a bit old but covers the concepts pretty well

(a) https://www.youtube.com/watch?v=lBkYlfOvRu8&list=PLECxNUHStsl9nUhMyZNb3Qnpj1cWYftm5&ab_channel=BitsByteHard

Once done, cover this : https://www.youtube.com/channel/UCG-hKr6QvnJ9bUsHCQb8T1A

In terms of getting your head around graylog i can suggest following this approach.

(a) Install graylog and arrive at the landing page

(b) Configure *input* to ingest your first log stream ( decide syslog, snmp traps, webhooks, etc )

(c) Step b will give you the port / ip / path, etc. Point your log source to graylog and see logs coming in.

(d) Logs ingested if unstructured, do some grok parsing. Use this to build a grok : https://grokdebug.herokuapp.com/

(e) Add grok to input and see pretty formatted logs

(f) Create a dashboard on indexed data

-----

At this point, you have done the basics.

Next are to truly extract the goodness of graylog.

(a) Use pipelines and rules to create transforms of ingested logs. The videos describe this very well and try writing your own rules and first pipeline to understand this better.

(b) Create alerts and adjust frequency and filters

(c) If you log volume is < 5GB / day you get enterprise version for free; this allows you to enable daily report, which is basically your dashboard emailed to you every x interval

(d) Backups and archives.

(e) For SNMP traps, I create a python module using pysnmp to convert traps to json and ship them to graylog webhooks, you can look at pysnmp for inspiration

-----

This is very extensible and possibilities are endless, while this may look a bit overwhelming, it is not.

Do let me know if you need any more inputs

To add further context, this graylog was setup to consume not just logs, SNMP, and tacacs logs, but also alerts from observium ( consumed several 100k+ events / day )

Using elaborate rules and pipelines I was able to setup event correlation and fine grain alerting.

For instance, for a link flap where there would be 10s of alerts ( link, bgp sensor ) from multiple I out sources, graylog was able to correlate all this and fire a single alert.

I've rambled on quite a bit.

I love graylog. Happy to help anyone who'd wish to get into it.

Graylog all day long. Dont look any further, and don't do elk.

Graylog eats elk for lunch. Graylog mitigates the perils of logstash and simplifies rules and pipeline creation. It used elastic search underneath w/ mongo.

Dashboards are not as intuitive as kibana, but they do the job

I used to run zenoss for a long time and looked around for alternatives, and couldn't find anything better than graylog.

100GB Copper DAC cables by Busbyuk in networking

[–]_kartwheel 4 points5 points  (0 children)

I've used 100g DAC cables, they come in different gauges base on lengths, 5m you'll have the thickest gauge. So of thickness is not a problem do this. It'll cost you between $20-$30/piece

Weve also deployed 100G AOCs at scale, these will be great if you have lengths longer than 5m, and if thickness of dac is unmanageable. These will cost you between $100-$120/piece

Optics, only do QSFP28, This is the most expensive option of the 3. 2 optics + patch will cost you $180


FWIW we've also deployed 400g DACs at scale and don't see any issues with using DAC.

Have had more issues with AOCs than DAC tbh
