This document contains results of automated tests of the waveform
availability of European EIDA stations and the responsiveness of the
EIDA servers to metadata requests.
Description of waveform
test program
Availability test of EIDA stations using Python obspy library.
Conducts random waveform requests to single channels of EIDA
stations.
One request per minute.
Requested time span randomly selected from last year, span length
between 60 and 600 s.
Station randomly selected from the subset of unrestricted European
EIDA stations offering at least one out of channels HHZ, BHZ, EHZ or
SHZ.
Request full station metadata from selected station and choose
channel randomly, restricted to channels HH?, BH?, EH? and SH?.
On successful request apply a restitution to the waveform data.
Evaluate and store result of request in a file database.
Plot and statistically analyze content of file database.
The code does not use the waveform catalog, therefore empty waveform
returns are due to data gaps or due to problems in data access and
delivery.
Statistics on waveform tests
Statistics on random requests between 01-08-2025 and 01-11-2025 00:32
using station metadata valid since 01-11-2024.
Color coded plot of evaluated EIDA stations. Shows results of 124839
random requests between 01-08-2025 and 01-11-2025. The availability
displayed is computed as the relative number of request results with
status OK (see table below) compared to the number of all
requests to this station.

Failure rate of inventory
requests
This section contains results of inventory test requests on network,
station and channel level. A few times per hour all servers get direct
metadata requests followed by a metadata request using the routing
client of obspy. It is checked whether all servers respond to the direct
requests and whether all servers contribute to the routed request. The
following results refer to tests carried out since 04-10-2025
00:32:02.
