Hardware upgrade and server migration

Hi there,

we will migrate our data acquisition machines serving https://swarm.hiveeyes.org/ and https://weather.hiveeyes.org/ to a new host system running on a PX61-SSD.

The data acquisition will be interrupted during the migration phase, we ask for your understanding.


Looks like the migration was successful as everything feels like its working. Please let us know if you encounter any problems when using the system.

Have fun!

I have seen the rental costs! ;-) So let us know your bank details, PayPal address, Amazon wish list, favorite beer brand (but I fear in case we refund the monthly cost with beer …), fave stores for gift coupon …!


Hi Clemens,

thank you so much! We are considering to create a Liberapay (Wikipedia) account soon and will be happy to accept donations there.

Until then: Just enjoy the improved performance.

Technical data

Some words about the technical data of the data acquisition machines. The resource bump should give us enough headroom for the upcoming months, nevertheless we will continue to add more system resources on demand when needed.

elbanco (swarm.hiveeyes.org)

This machine collects and processes low-volume measurement data from beekeepers.

$ nproc

$ free -m
             total       used       free
Mem:          8037       7987         50
Swap:         3071         17       3054

eltiempo (weather.hiveeyes.org)

This machine collects and processes high-volume measurement data from different upstream data collections, providers and services.

$ nproc

$ free -m
              total        used        free
Mem:          24082       10909        5305
Swap:          4095          96        3999

We also switched the /var filesystem where the InfluxDB database stores its data to XFS:

$ mount | grep '/var'
/dev/xvda5 on /var type xfs (rw,relatime,attr2,inode64,noquota)

$ df -h /var
Filesystem      Size  Used Avail Use% Mounted on
/dev/xvda5       50G   17G   34G  34% /var
