NAME
LOGARCHIVE - Performance Co-Pilot archive formats
DESCRIPTION
Performance Co-Pilot (PCP) archives store historical values about
arbitrary metrics recorded from a single host. Archives are
machine independent and self-contained - all metric data and
metadata required for off-line or off-site analysis is held
within an archive.
The format is stable in order to allow long-term historical
storage and processing by PMAPI(3) client tools. However some
format variants are supported over time, and currently Versions 2
and 3 are supported. The mandate is that PCP will provide long-
term backwards compatibility, so an archive created on any
version of PCP can be read on that version of PCP and all
subsequent versions of PCP. The exception is Version 1 that was
retired in the PCP Version 2.0 release in May 1998.
Archives may be read by most PCP client tools, using the
-a/--archive NAME option, or dumped raw by pmlogdump(1).
Archives are created primarily by pmlogger(1), however they can
also be created using the LOGIMPORT(3) programming interface.
Archives may be merged, analyzed, modified and subsampled using
pmlogreduce(1), pmlogsummary(1), pmlogrewrite(1) and
pmlogextract(1). In addition, PCP archives may be examined in
sets or grouped together into ``archive folios'', which are
created and managed by the mkaf(1) and pmafm(1) tools.
An archive consists of several physical files that share a common
arbitrary prefix, e.g. myarchive.
myarchive.0, myarchive.1, ...
One or more data volumes containing the metric values and
any error codes encountered during metric sampling.
Typically the largest of the files and may grow very
rapidly, depending on the selection of metrics to be
logged by pmlogger(1) and the sampling intervals being
used.
myarchive.meta
Information for PMAPI functions such as pmLookupName(3),
pmLookupDesc(3), pmLookupLabels(3) and pmLookupInDom(3).
The metadata file may grow sporadically as logged metrics,
instance domains and labels vary over time.
myarchive.index
A temporal index, mapping timestamps to byte offsets in
the other files.
COMMON FEATURES
All three types of files have a similar record-based structure, a
convention of network byte-order (big-endian) encoding, and
32-bit fields for tagging/padding for those records. Strings are
stored as 8-bit characters without assuming a specific encoding,
so normally ASCII. See also the __pmLog* types in
src/include/pcp/libpcp.h.
RECORD FRAMING
The volume and .meta files are divided into self-identifying
records.
┌────────┬────────┬─────────────────────────────────────────────┐
│ Offset │ Length │ Name │
├────────┼────────┼─────────────────────────────────────────────┤
│ 0 │ 4 │ N, length of record, in bytes, including │
│ │ │ this field │
│ 4 │ N-8 │ record payload, usually starting with a │
│ │ │ 32-bit record type tag │
│ N-4 │ 4 │ N, length of record (again) │
└────────┴────────┴─────────────────────────────────────────────┘
ARCHIVE LABEL
All three types of files begin with an ``archive label'' header,
which identifies the host name, starting timestamp and timezone
information; all referring to the host that was the source of the
performance data (which may be different to the host where
pmlogger(1) was running).
The ``archive label'' format differs between Version 2 and
Version 3, with the latter providing enhanced timestamps (64-bit
encoding of the seconds part and nanosecond precision) and some
additional fields.

└────────┴────────┴──────────────────────────────────────────────┘
The ``archive feature bits'' are intended to encode possible
future extensions or differences to the on-disk structure or the
the archive semantics. At this stage there are no such features,
but if they are introduced at some point in the future, there
will be associated PM_LOG_FEATURE_XXX macros added to the
<pcp/pmapi.h> header file.
All fields, except for the ``current archive volume number'',
match for all files in a single PCP archive.
ARCHIVE VOLUME (.0, .1, ...) RECORDS
pmResult
After the archive label record, an archive volume file contains
one or more records, each providing metric values corresponding
to the pmResult from one pmFetch(3) operation. The record size
may vary according to number of metrics being fetched and the
number of instances in the associated instance domains.
For Version 2 the file size is limited to 2GiB, due to storage of
32-bit byte offsets within the temporal index. For Version 3 the
file size is limited to 8191PiB, due to storage of 62-bit byte
offsets within the temporal index.
The pmResult format differs between Version 2 and Version 3, with
the latter providing enhanced timestamps (64-bit encoding of the
seconds part and nanosecond precision).

└─────────┴────────┴───────────────────────────────────────────┘
Records with a ``number of metrics'' equal to zero are ``mark
records'', and represent interruptions, missing data, or time
discontinuities in logging.
pmValueSet
This subrecord represents the values for one metric at one point
in time.
┌────────┬────────┬────────────────────────────────────────────────┐
│ Offset │ Length │ Name │
├────────┼────────┼────────────────────────────────────────────────┤
│ 0 │ 4 │ Performance Metrics Identifier (PMID) │

└────────┴────────┴────────────────────────────────────────────────┘
The metadata describing metrics is found in the .meta file where
the entries are not timestamped, as the metadata is assumed to be
unchanging throughout an archive.
pmValue
This subrecord represents one value for one instance of a metric
at one point in time. It is a variant type, depending on the
parent pmValueSet's value format field. This allows small
numbers to be encoded compactly, but retain flexibility for
larger or variable length data to be stored later in the pmResult
record in a pmValueBlock subrecord.
┌────────┬────────┬───────────────────────────────────────────────┐
│ Offset │ Length │ Name │
├────────┼────────┼───────────────────────────────────────────────┤
│ 0 │ 4 │ internal instance identifier (or │
│ │ │ PM_IN_NULL=-1 for singular metrics) │
│ 4 │ 4 │ value (INSITU) or │
│ │ │ offset in pmResult to our pmValueBlock (DPTR) │
└────────┴────────┴───────────────────────────────────────────────┘
The metadata describing the instance domain for metrics is found
in the .meta file. Since the numeric mappings may change during
the lifetime of the logging session, it is important to match up
the timestamp of the measurement record with the corresponding
instance domain record. That is, the instance domain
corresponding to a measurement at time T is the instance domain
observation for the metric's instance domain with largest
timestamp T' <= T.
pmValueBlock
Instances of this subrecord are placed at the end of the
pmValueSet, after all the pmValue subrecords. If (and only if)
needed, they are padded at the end to the next 32-bit boundary.
┌────────┬────────┬────────────────────────────────────────────────┐
│ Offset │ Length │ Name │
├────────┼────────┼────────────────────────────────────────────────┤
│ 0 │ 1 │ value type (same as pmDesc.type) │
│ 1 │ 3 │ 4 + N, the length of the subrecord │
│ 4 │ N │ bytes that make up the raw value │
│ 4+N │ 0-3 │ padding (not included in the 4+N length field) │
└────────┴────────┴────────────────────────────────────────────────┘
Note that for PM_TYPE_STRING, the length includes an explicit
NULL terminator byte. For PM_TYPE_EVENT, the value byte string
is further structured. Refer to PMDAEVENTARRAY(3) for more
information about how arrays of event records are packed inside a
pmResult container.
METADATA FILE (.meta) RECORDS
After the archive label record, the metadata file contains
interleaved metric description records, timestamped instance
domain records, timestamped label records (for context, instance
domain and metric labels) and (help) text records. Unlike the
data volumes, these records are not forced to 32-bit alignment.
For Version 2 the file size is limited to 2GiB, due to storage of
32-bit byte offsets within the temporal index. For Version 3 the
file size is limited to 8191PiB, due to storage of 62-bit byte
offsets within the temporal index.
See also libpcp/src/logmeta.c.
Metric Descriptions
Instances of this (pmDesc) record provide the description or
metadata for each metric appearing in the PCP archive. This
metadata includes the metric's PMID, data type, data semantics,
instance domain identifier (or PM_INDOM_NULL for singular metrics
with only one value) and a set of (1 or more) names.
┌────────┬────────┬───────────────────────────────────────────────────┐

├────────┼────────┼───────────────────────────────────────────────────┤
│ 0 │ 4 │ tag, TYPE_DESC=1 │

│ 28 │ 4 │ N: number of bytes in this name │
│ 32 │ N │ bytes of the name, no NULL terminator nor padding │
│ 32+N │ 4 │ N2: number of bytes in next name │
│ 36+N │ N2 │ bytes of the name, no NULL terminator nor padding │
│ ... │ ... │ ... │
└────────┴────────┴───────────────────────────────────────────────────┘
Instance Domains
A set-valued metric is defined over an instance domain, which
consists of an instance domain identifier (will have already been
mentioned in a prior pmDesc record), a count of the number of
instances and a map that defines the association between internal
instance identifiers (integers) and external instance names
(strings).
Because instance domains can change over time, the instance
domain also requires a timestamp, and the same instance domain
can occur multiple times within the .meta file. The timestamps
are used to search for the temporally correct instance domain
when decoding pmResult records from the archive data volumes, or
answering metadata queries against the instance domain.
The instance domain format differs markedly between Version 2 and
Version 3. Version 3 provides enhanced timestamps (64-bit
encoding of the seconds part and nanosecond precision) and
introduces a new ``delta'' instance domain format that encodes
differences between the previous observation of the instance
domain and the current state of the instance domain.

└──────────┴────────┴───────────────────────────────────────────────┘
The ``delta'' instance domain record in Version 3 uses the same
physical structure as the ``full'' instance domain above with the
following differences:
* The tag is TYPE_INDOM_DELTA=6.
* The ``number of instances in domain'' field becomes the sum of
the number of instances added and the number of instances
deleted.
* Deleted instances are encoded with the string offset set to -1
and there is no corresponding string table entry.
* Added instances are encoded exactly the same way.
The ``delta'' instance domain format is used to provide a more
compact on-disk encoding for instance domains that have a large
number of instances and are subject to frequent small changes,
e.g. the instance domain of process ids, as exported by
pmdaproc(1).
For ``full'' instance domain records the instance domain replace
the previous instance domain: prior records are not searched for
instance domain metadata queries after this timestamp.
Each instance domain in a Version 3 archive must have an initial
``full'' instance domain record. Subsequent records for the same
instance domain can be the `full'' or the ``delta'' variant. Any
instance mentioned in the prior observation of an instance domain
that is not mentioned in the ``delta'' instance domain record is
assumed to continue to exist for the current observation of the
instance domain.
Labels for Contexts, Instance Domains and Metrics
Instances of this (pmLogLabelSet) record provide sets of label-
name:label-value pairs associated with labels of the context,
instance domains and individual performance metrics - refer to
pmLookupLabels(3) for further details.
Any instance domain identifier will have already been mentioned
in a prior pmDesc record.
As new labels can appear during an archiving session, these
records are timestamped and must be searched when decoding
pmResult records from the archive data volumes. The
pmLogLabelSet format differs between Version 2 and Version 3,
with the latter providing enhanced timestamps (64-bit encoding of
the seconds part and nanosecond precision).

Records of this form replace the existing labels for a given
label type: prior records are not searched for resolving that
class of label in measurements after this timestamp.
The individual labelset array entries are variable length,
depending on the number of labels present within that set. These
entries contain the instance identifiers (in the case of type
PM_LABEL_INSTANCES labels), lengths and offsets of each label
name and value, and also any flags set for each label.

INDEX FILE (.index) RECORDS
After the archive label record, the temporal index file contains
a plainly concatenated, unframed group of tuples, which relate
timestamps to the byte offsets in the volume and .meta files.
These records are fixed size, fixed format, and are not enclosed
in the standard length/payload/length wrapper: they take up the
entire remainder of the .index file after the archive label
record.
The temporal index file provides a rapid way of seeking to a
particular point of time within an archive for both the
performance metric values and the associated metadata.
See also libpcp/src/logutil.c.
The index format differs between Version 2 and Version 3, with
the latter providing enhanced timestamps (64-bit encoding of the
seconds part and nanosecond precision) and 64-bit byte offsets.

└────────┴────────┴───────────────────────────────────────────┘
Since the temporal index is optional, and exists only to speed up
time-based random access to metrics and their metadata, the index
records are emitted only intermittently. An archive reader
program should not presume any particular rate of data flow into
the index. However, common events that may trigger a new
temporal index record include changes in instance domains,
switching over to a new archive volume, and starting or stopping
logging. One reliable invariant however is that, for each index
entry, there are to be no meta or archive volume records with a
timestamp after that in the index, but physically before the
associated byte offset in the index.
