The following stats are avalible in both JSON Syslog and Promethues ### push_pcap_status - for every PCAP file generated This is the top level full status of an individual PCAP file. | Value | Desc | | --- | --- | | 1 | If all Local Remote and Match statuses are good | | 0 | One or more of Local, Remote, match status is in a failure condition | ### push_pcap_local_bps - for every PCAP file generated This is the data rate for a specific PCAP write this to the local storage device. ```plaintext push_pcap_local_bps = total bytes * 8 / total time ``` ### push_pcap_local_byte - for every PCAP file generated This is the total bytes for a PCAP write to the local storage device. ### push_pcap_local_status - for every PCAP file generated Indicates the status of the specific PCAP file. Table below shows the meaning | Value | Desc | | --- | --- | | 1 | Local file has been generated and is > 0 bytes | | 0 | Failure condition | ### push_pcap_local_time - for every PCAP file generated The number of seconds it took to create the local file. NOTE: this is an integer value ### push_pcap_localremote_size_missmatch - for every PCAP file generated Indicates the status of local vs remote PCAP file comparision | Value | Desc | | --- | --- | | 1 | Local and Remote file are > 0 bytes Local number of bytes == Remote number of bytes | | 0 | Failure condition | ### push_pcap_remote_bps - for every PCAP file generated This is the data rate for a specific PCAP write this to the remote storage device. ```plaintext push_pcap_remote_bps = total bytes * 8 / total time ``` ### push_pcap_remote_byte - for every PCAP file generated This is the total bytes for a PCAP written to the remote storage device. ### push_pcap_remote_status - for every PCAP file generated Indicates the status of the specific PCAP file. Table below shows the meaning | Value | Desc | | --- | --- | | 1 | Remote file has been generated and is > 0 bytes | | 0 | Failure condition | ### push_pcap_remote_time - for every PCAP file generated The number of seconds it took to create and copy the PCAP from the local storage location to the remote storage location. NOTE: this is an integer value --- ## Disk Monitoring FMADIO provides detailed disk monitoring logs, enabling monitoring teams to stay head of potential disk hardware related issues before ### DiskPresent (disk_valid) Indicates a disk is present at the specified label.
