**Problem Description** Pixie is unable to capture syscalls with an [iovcnt](https://github.com/pixie-io/pixie/blob/755f138bac4e97f5628a44f58454bfce2ab2f9ad/src/stirling/source_connectors/socket_tracer/bcc_bpf/socket_trace.c#L38) `>42` or a [message size](https://github.com/pixie-io/pixie/blob/755f138bac4e97f5628a44f58454bfce2ab2f9ad/src/stirling/source_connectors/socket_tracer/bcc_bpf_intf/socket_trace.h#L130) `>120 KiB` . These variables are set conservatively to keep the instruction count below...
Summary: Adds a bpf test for HTTP that triggers the gap condition `LoopLimitExceeded` based on a NodeJS application submitted in community slack. It submits an iovec with 257 elements, which...
Summary: Adds metric to keep track of the number of bytes rendered unparseable due to the presence of a gap (i.e. the bytes we discard because we can't process the...
Summary: Adds prometheus counter to record the bytes lost due to gaps from bpf and the reason for the gap on a per protocol basis. Type of change: /kind feature...
Summary: Updates and adds tests for lazy parsing related to spike capacity, data loss metrics and filler bytes. Type of change: /kind feature Test Plan: Existing and new tests pass.
Summary: Adds vizier feature flag for lazy parsing (off by default) which enables lazy parsing and disables adding filler events to incomplete chunks for supported protocols. Currently only HTTP lazy...
Summary: Adds metadata to the `always_contiguous_data_stream_buffer` to keep track of gap and filler locations. This forms the basis of tracking the number of bytes rendered unparseable due to the presence...
Summary: Instead of relying on filler events with large null byte allocations, we should parse as far as possible up to the gap for incomplete events. Such lazy parsing lets...
Hi, I just installed Pixie self hosted cloud + Pixie's Vizier. (both are in the same cluster) I see the cluster registered in the UI but when I'm trying to...
