Subject: usertools/telemetry: add JSON pretty print
[ upstream commit 66542840dfd184c06813e6740664b280ef77d4e0 ]
Currently, the dpdk-telemetry.py show JSON in raw format under
interactive mode, which is not good for human reading.
E.g. The command '/ethdev/xstats,0' will output:
{"/ethdev/xstats": {"rx_good_packets": 0, "tx_good_packets": 0,
"rx_good_bytes": 0, "tx_good_bytes": 0, "rx_missed_errors": 0,
"rx_errors": 0, "tx_errors": 0, "rx_mbuf_allocation_errors": 0,
"rx_q0_packets": 0,...}}
This patch supports JSON pretty print by adding extra indent=2
parameter under interactive mode, so the same command will output:
{
"/ethdev/xstats": {
"rx_good_packets": 0,
"tx_good_packets": 0,
"rx_good_bytes": 0,
"tx_good_bytes": 0,
"rx_missed_errors": 0,
"rx_errors": 0,
"rx_mbuf_allocation_errors": 0,
"rx_q0_packets": 0,
...
}
}
Note: the non-interactive mode is made machine-readable and remains the
original way (it means don't use indent to pretty print).
