Types

type Client

type Client struct {
	log.BasicLogable
	io.Closer
	// contains filtered or unexported fields
}

Client is the client-view of the server.

func NewClient

func NewClient(ctx context.Context, cfg *ClientConfig) (*Client, error)

NewClient returns a new client-view of the server specified by the configuration cfg.

func (*Client) IsLogName

func (c *Client) IsLogName(ctx context.Context, name string) (bool, error)

IsLogName returns true iff the given string is a log name.

func (*Client) LogNames

func (c *Client) LogNames(ctx context.Context) ([]string, error)

LogNames returns the log names.

func (*Client) LogNamesWithMatches

func (c *Client) LogNamesWithMatches(ctx context.Context, cond monitor.NameMatches) ([]string, error)

LogNamesWithMatches is the same as LogNames, with the exception that log names are filtered against the conditions 'cond'.

func (*Client) Stream

func (c *Client) Stream(ctx context.Context, name string, start *monitor.Time, finish *monitor.Time) (monitor.Iterator, error)

Stream returns an iterator down which entries from the log 'name' are passed. Only entries falling into the range determined by start and finish will be returned. If start is unassigned then the start of the log will be used; if end is unassigned then no end is used. The caller should ensure that the returned Iterator is closed, otherwise a resource leak will result.

func (*Client) StreamWithMatches

func (c *Client) StreamWithMatches(ctx context.Context, name string, start *monitor.Time, finish *monitor.Time, cond monitor.Matches) (monitor.Iterator, error)

StreamWithMatches is the same as Stream, with the exception that entries are filtered against the conditions 'cond'.

type ClientConfig

type ClientConfig struct {
	Address     *address.Address // The address to connect to
	SSLDisabled bool             // Disable SSL?
	SSLCert     []byte           // The SSL certificate (if any)
}

ClientConfig describes the configuration options we allow a user to set on a client connection.

func DefaultConfig

func DefaultConfig() *ClientConfig

DefaultConfig returns a new client configuration initialised with the default values.

The initial default value for the host and port will be read from the environment variable

PCAS_MONITOR_ADDRESS = "hostname[:port]" or "ws://host/path"

on package init.

func SetDefaultConfig

func SetDefaultConfig(c *ClientConfig) *ClientConfig

SetDefaultConfig sets the default client configuration to c and returns the old default configuration. This change will be reflected in future calls to DefaultConfig.

func (*ClientConfig) Copy

func (c *ClientConfig) Copy() *ClientConfig

Copy returns a copy of the configuration.

func (*ClientConfig) URI

func (c *ClientConfig) URI() string

URI returns the URI connection string.

Note that the returned string may differ slightly from the value returned c.Address.URI(). For example, if c.Address omits a port number, an appropriate default port number is used here.

func (*ClientConfig) Validate

func (c *ClientConfig) Validate() error

Validate validates the client configuration, returning an error if there's a problem.

type Option

type Option interface {
	// contains filtered or unexported methods
}

Option sets options on a server.

func Connection

func Connection(c monitor.Connection) Option

Connection is the connection from which log messages will be read.

func SSLCertAndKey

func SSLCertAndKey(crt []byte, key []byte) Option

SSLCertAndKey adds the given SSL public certificate and private key to the server.

type Server

type Server struct {
	log.SetLoggerer
	grpcutil.Server
}

Server handles client communication.

func NewServer

func NewServer(options ...Option) (*Server, error)

NewServer returns a new monitord server.
